Twitter, officially known asX since 2023, is asocial networking service. It is one of the world's largestsocial media platforms and one of themost-visited websites.[6][7] Users can share short text messages, images, and videos inshort posts commonly known as "tweets" (officially "posts") andlike other users' content.[8] The platform also includesdirect messaging, video and audio calling, bookmarks, lists, communities, a chatbot (Grok), job search,[9] and Spaces, a social audio feature. Users can vote on context added by approved users using theCommunity Notes feature.
Twitter was created in March 2006 byJack Dorsey,Noah Glass,Biz Stone, andEvan Williams, and was launched in July of that year. Twitter grew quickly; by 2012 more than 100 million users produced 340 million daily tweets.[10] Twitter, Inc., was based in San Francisco, California, and had more than 25 offices around the world.[11] A signature characteristic of the service initially was that posts were required to be brief. Posts were initially limited to 140 characters, which was changed to 280 characters in 2017. The limitation was removed for subscribed accounts in 2023.[12] 10% of users produce over 80% of tweets.[13][14] In 2020, it was estimated that approximately 48 million accounts (15% of all accounts) were run byinternet bots rather than humans.[15]
The service is owned by the American companyX Corp., which was established to succeed the prior ownerTwitter, Inc. in March 2023 following theOctober 2022 acquisition of Twitter byElon Musk for US$44 billion. Musk stated that his goal with the acquisition was to promotefree speech on the platform.Since his acquisition, the platform has been criticized for enabling the increased spread ofdisinformation[16][17][18] andhate speech.[19][20][21]Linda Yaccarino succeeded Musk as CEO on June 5, 2023, with Musk remaining as the chairman and thechief technology officer.[22][23][24] In July 2023, Musk announced that Twitter would be rebranded to "X" and the bird logo would be retired,[25][26] a process which was completed by May 2024. Since Musk's takeover, data from app-tracking firms has shown that global usage of Twitter has declined by approximately 15%, compared to a decline of 5–10% in some other social media sites.[27][28][29] The platform has disputed that usage has dropped at all, with Musk claiming without evidence that membership had grown to 600 million users as of a May 2024[update] tweet.[30]
In March 2025,X Corp. was acquired byxAI, Musk's artificial intelligence company. The deal, an all-stock transaction, valued X at $33 billion, with a full valuation of $45 billion when factoring in $12 billion in debt. Meanwhile, xAI itself was valued at $80 billion.[31][32]
Jack Dorsey claims to have introduced the idea of an individual using an SMS service to communicate to a small group in 2006.[33] The originalproject code name for the service wastwttr, an idea that Williams later ascribed toNoah Glass,[34] inspired byFlickr and the five-character length of American SMSshort codes. The decision was also partly due to the fact that the domain twitter.com was already in use, and it was six months after the launch of twttr that the crew purchased the domain and changed the name of the service toTwitter.[35] Work on the project started in February 2006.[36]
The first Twitter prototype, developed by Dorsey and contractor Florian Weber, was used as an internal service forOdeo employees.[36] The full version was introduced publicly on July 15, 2006.[37] In October 2006,Biz Stone,Evan Williams, Dorsey, and other members of Odeo formed Obvious Corporation and acquired Odeo from the investors and shareholders.[38] Williams fired Glass, who was silent about his part in Twitter's startup until 2011.[39] Twitter spun off into its own company in April 2007.[40] Thetipping point for Twitter's popularity was the 2007South by Southwest Interactive (SXSWi) conference. During the event,Twitter usage increased from 20,000 tweets per day to 60,000.[41]
The company experienced rapid initial growth thereafter. In 2009, Twitter won the "Breakout of the Year"Webby Award.[42][43] In February 2010, Twitter users were sending50 million tweets per day.[44] By March 2010, the company recorded over 70,000 registered applications.[45] In June 2010, about65 million tweets were posted each day, equaling about 750 tweets sent each second, according to Twitter.[46] As noted onCompete.com, Twitter moved up to the third-highest-rankingsocial networking site in January 2009 from its previous rank of twenty-second.[47]

From September through October 2010, the company began rolling out "New Twitter", an entirely revamped edition of twitter.com. Changes included the ability to see pictures and videos without leaving Twitter itself by clicking on individual tweets which contain links to images and clips from a variety of supported websites, including YouTube andFlickr, and a complete overhaul of the interface.[48] In 2019, Twitter was announced to be the 10th most downloaded mobile app of the decade, from 2010 to 2019.[48]
On March 21, 2012, Twitter celebrated its sixth birthday by announcing that it had 140 million users, a 40% rise from September 2011, who were sending 340 million tweets per day.[49][50] On June 5, 2012, a modified logo was unveiled through the company blog, removing the text to showcase the slightly redesigned bird as the sole symbol of Twitter.[51][52] On December 18, 2012, Twitter announced it had surpassed 200 millionmonthly active users.[citation needed] In September 2013, the company's data showed that 200 million users sent over 400 million tweets daily, with nearly 60% of tweets sent from mobile devices.[53]
In April 2014, Twitter underwent a redesign that made the site resemble Facebook somewhat, with a profile picture and biography in a column left to the timeline, and a full-width header image withparallax scrolling effect.[c][54] Late in 2015, it became apparent that growth had slowed, according to Fortune,[55] Business Insider,[56] Marketing Land[57] and other news websites including Quartz (in 2016).[58] In 2019, Twitter released another redesign of its user interface.[59] By the start of 2019[update], Twitter had more than 330 million monthly active users.[60] Twitter then experienced considerable growth during theCOVID-19 pandemic in 2020.[61] The platform also was increasingly used formisinformation related to the pandemic.[62] Twitter started marking tweets which contained misleading information, and adding links to fact-checks.[63]
In 2021, Twitter began the research phase ofBluesky, anopen source decentralized social media protocol where users can choose whichalgorithmic curation they want.[64][65] The same year, Twitter also released Twitter Spaces, a social audio feature;[66][67] "super follows", a way to subscribe to creators for exclusive content;[68] and a beta of "ticketed Spaces", which makes access to certain audio rooms paid.[69] Twitter unveiled a redesign in August 2021, with adjusted colors and a new Chirp font, which improves the left-alignment of most Western languages.
Elon Musk completedthe acquisition of Twitter in October 2022; Musk acted asCEO of Twitter until June 2023 when he was succeeded byLinda Yaccarino. In a move that, despite Yaccarino's accession, was widely attributed to Musk,[70][71] Twitter was rebranded to X on July 23, 2023,[72] and its domain name changed from twitter.com to x.com on May 17, 2024.[73]
Now operating as X, the platform closely resembles its predecessor but includes additional features such as long-form texts,[74] account monetization options,[75] audio-video calls,[76] integration withxAI'sGrok chatbot,[77] job search,[78] and arepurposing of the platform's verification system as a subscription premium.[79] Several legacy Twitter features were removed from the site after Musk acquired Twitter, including Circles,[80]NFT profile pictures,[81] and the experimentalpronouns in profiles feature.[82] Musk aims to transform X into an "everything app", akin toWeChat.[83]

Tweets
"Twitter hashtag" redirects here. For more about hashtags, seeHashtag.
Tweets were publicly visible by default, but senders can restrict message delivery to only their followers. Users can mute users they do not wish to interact with, block accounts from viewing their posts, and remove accounts from their followers list.[90][91][92] Users can post via the Twitter website, compatible external applications (such as forsmartphones), or byShort Message Service (SMS) available in certain countries.[93] Users may subscribe to other users' posts—this is known as "following" and subscribers are known as "followers"[94] or "tweeps", a portmanteau of Twitter and peeps.[95] Individual posts can be forwarded by other users to their own feed, a process known as a "retweet" (officially "repost"). In 2015, Twitter launched "quote tweet" (originally called "retweet with comment" and officially just "quote"),[96] a feature which allows users to add a comment to their post, imbedding one post in the other.[97] Users can also "like" (formerly "favorite") individual tweets.[98]
The counters for likes, retweets, and replies appear next to the respective buttons in timelines such as on profile pages and search results. Counters for likes and reposts exist on a post's standalone page too. Since September 2020, quote tweets, formerly known as "retweet with comment", have their own counter on their post page.[96] Until the legacy desktop front end that was discontinued in 2020, a row with miniature profile pictures of up to ten liking or retweeting users was displayed (earliest documented implementation in December 2011 overhaul), as well as a tweet reply counter next to the according button on a tweet's page.[99][100]
Twitter allows users to update their profile via their mobile phones either by text messaging or by apps released for certain smartphones and tablets.[101][non-primary source needed] Twitter announced in a tweet on September 1, 2022, that the ability to edit a tweet was being tested for select users. Eventually, allTwitter Blue subscribers would be able to use the feature.[102] Users can group posts together by topic or type by use ofhashtags – words or phrases prefixed with a "#" sign. Similarly, the "@" sign followed by ausername is used for mentioning or replying to other users.[103] In 2014, Twitter introduced hashflags, special hashtags that automatically generate a customemoji next to them for a certain period of time.[104] Hashflags may be generated by Twitter themselves[105] or be purchased by corporations.[106] To repost a message from another user and share it with one's own followers, a user can click the repost button within the post. Users can reply to other accounts' replies. Users can hide replies to their messages and select who can reply to each of their tweets before sending them: anyone, accounts who follow the post's author, specific accounts, or none.[107][108]
The original, strict 140 character limit was gradually relaxed. In 2016, Twitter announced that attachments, links, and media such as photos, videos, and the person's handle, would no longer count; a user photo post used to count for around 24 characters.[109][110] In 2017, Twitter handles were similarly excluded.[111] The same year, Twitter doubled its historical 140-character-limitation to 280.[112] Under the new limit,glyphs are counted as a variable number of characters, depending upon the script they are from.[112] In 2023, Twitter announced that Twitter Blue users could create posts with up to 4,000 characters in length.[113]
t.co is aURL shortening service created by Twitter.[114] It is only available for links posted to Twitter and not available for general use.[114] All links posted to Twitter use a t.co wrapper.[115] Twitter intended the service to protect users from malicious sites,[114] and to use it to track clicks on links within tweets.[114][116] Twitter had previously used the services of third partiesTinyURL andbit.ly.[117]
In June 2011, Twitter announced its own integrated photo-sharing service that enables users to upload a photo and attach it to a Tweet right from Twitter.com.[118] Users now also have the ability to add pictures to Twitter's search by adding hashtags to the tweet.[119] Twitter also plans to provide photo galleries designed to gather and syndicate all photos that a user has uploaded on Twitter and third-party services such asTwitPic.[119] On March 29, 2016, Twitter introduced the ability to add a caption of up to 480 characters to each image attached to a tweet,[120][121] accessible via screen reading software or by hovering the mouse above a picture insideTweetDeck. In April 2022, Twitter made the ability to add and view captions globally available. Descriptions can be added to any uploaded image with a limit of 1000 characters. Images that have a description will feature a badge that saysALT in the bottom left corner, which will bring up the description when clicked.[122]
In 2015, Twitter began to roll out the ability to attach poll questions to tweets. Polls are open for up to 7 days, and voters are not personally identified.[123] In Twitter's early years, users could communicate with Twitter using SMS. Twitter discontinued this feature in most countries in April 2023, after hackers had exposed vulnerabilities in the feature.[124][125]
Twitter Spaces is asocial audio feature that enables users to host or participate in a live-audio virtual environment calledspace for conversation. A maximum of 13 people are allowed onstage. The feature was initially limited to users with at least 600 followers, but since October 2021, any Twitter user can create a Space.[131]
In March 2020, Twitter began to test astories feature known as "fleets" in some markets,[132][133] which officially launched on November 17, 2020.[134][135] Fleets could contain text and media, are only accessible for 24 hours after they are posted, and are accessed within the Twitter app;[132] Twitter announced it would start implementing advertising into fleets in June 2021.[136] Fleets were removed in August 2021; Twitter had intended for fleets to encourage more users to tweet regularly, but instead they were generally used by already-active users.[137]
Twitter introduced its "trends" feature in mid-2008, an algorithmic lists of trending topics among users.[138] A word or phrase mentioned can become "trending topic" based on an algorithm.[138] Because a relatively small number of users can affect trending topics through a concerted campaign, the feature has been the targeted of concerted manipulation campaigns.[138] While some campaigns are innocuous, others have promoted conspiracy theories or hoaxes, or sought to amplify extremist messages.[138] Some featured trends are globally displayed, while others are limited to a specific country.[138]
A 2021 study byEPFL researchers found that frequent "ephemeralastroturfing" efforts targeted at Trends; from 2015 to 2019, "47% of local trends in Turkey and 20% of global trends are fake, created from scratch by bots...The fake trends discovered includephishing apps, gambling promotions, disinformation campaigns, political slogans,hate speech against vulnerable populations and even marriage proposals."[139][140] TheMIT Technology Review reported that, as of 2022, Twitter "sometimes manually overrides particularly objectionable trends" and, for some trends, used both algorithmic and human input to select representative tweets with context.[138]
Lists
In late 2009, the "Twitter Lists" feature was added, making it possible for users to follow a curated list of accounts all at once, rather than following individual users.[94][141] Currently,[when?] lists can be set to either public or private. Public lists may be recommended to users via the general Lists interface and appear in search results.[142] If a user follows a public list, it will appear in the "View Lists" section of their profile, so that other users may quickly find it and follow it as well.[143] Private lists can only be followed if the creator shares a specific link to their list. Lists add a separate tab to the Twitter interface with the title of the list, such as "News" or "Economics".
Moments
In October 2015, Twitter introduced "Moments"—a feature that allows users to curate tweets from other users into a larger collection. Twitter initially intended the feature to be used by its in-house editorial team and other partners; they populated a dedicated tab in Twitter's apps, chronicling news headlines, sporting events, and other content.[144][145] In September 2016, creation of moments became available to all Twitter users.[146]
Algorithm
On October 21, 2021, a report based on a "long-running, massive-scale randomized experiment" that analyzed "millions of tweets sent between 1 April and 15 August 2020", found that Twitter'smachine learningrecommendation algorithm amplified right-leaning politics on personalized user Home timelines.[147]: 1 [148] The report compared seven countries with active Twitter users where data was available (Germany, Canada, the United Kingdom, Japan, France, and Spain) and examined tweets "from major political groups and politicians".[147]: 4 Researchers used the 2019 Chapel Hill Expert Survey (CHESDATA) to position parties on political ideology within each country.[147]: 4 The "machine learning algorithms", introduced by Twitter in 2016, personalized 99% of users' feeds by displaying tweets (even older tweets and retweets from accounts the user had not directly followed) that the algorithm had "deemed relevant" to the users' past preferences.[147]: 4 Twitter randomly chose 1% of users whose Home timelines displayed content in reverse-chronological order from users they directly followed.[147]: 2
Mobile
Twitter had mobile apps foriPhone,iPad, andAndroid.[149] In April 2017, Twitter introducedTwitter Lite, aprogressive web app designed for regions with unreliable and slow Internet connections, with a size of less than onemegabyte, designed for devices with limited storage capacity.[150][151]
X Premium (formerly Twitter Blue)
On June 3, 2021, Twitter announced a paid subscription service called Twitter Blue. FollowingTwitter's rebranding to "X", the subscription service was initially renamed to X Blue (or simply Blue), and, on August 5, 2023, was rebranded asX Premium (or simply Premium).[152][153] The subscription provides additional premium features to the service.[154][155] In November 2023 a "Premium+" subscription was launched, with a higher monthly fee giving benefits such as the omission of adverts on For You and Following feeds.[156]
In November 2022, Musk announced plans to add account verification and the ability to upload longer audio and video to Twitter Blue. A previous perk offering advertising-free news articles from participating publishers was dropped, but Musk stated that Twitter did want to work with publishers on a similar "paywall bypass" perk.[157][158][159] Musk had pushed for a more expensive version of Twitter Blue following his takeover, arguing that it would be needed to offset a decline in advertising revenue.[160] Twitter states that paid verification is required to help reduce fraudulent accounts.[161]
The verification marker was included in a premium tier of Twitter Blue introduced on November 9, 2022, priced at US$7.99 per month.[162] On November 11, 2022, after the introduction of this feature led to prominent issues involving accounts using the feature to impersonate public figures and companies, Twitter Blue with verification was temporarily suspended.[163][164] After about a month, Twitter Blue was relaunched on December 12, 2022, though for those purchasing the service through theiOS app store, the cost will be $10.99 a month as to offset the 30% revenue split that Apple takes.[165]
Twitter initially grandfathered users and entities that had gained verification due to their status as public figures, referring to them as "legacy verified accounts" that "may or may not be notable".[166] On March 25, 2023, it was announced that "legacy" verification status would be removed; a subscription will be required to retain verified status, costing $1,000 per-month for organizations (which are designated with a gold verified symbol),[161] plus an additional $50 for each "affiliate".[167][168] The change was originally scheduled for April 1, 2023, but was delayed to April 20, 2023, following criticism of the changes.[169] Musk also announced plans for the "For You" timeline to prioritize verified accounts and user followers only beginning April 15, 2023, and threatened to only allow verified users to participate in polls (although the latter change has yet to occur).[170]
Effective April 21, 2023, Twitter requires companies to participate in the verified organizations program to purchase advertising on the platform, although companies that spend at least $1,000 on advertising per-month automatically receive membership in the program at no additional cost.[161]
From April 25, 2023, verified users are now prioritized in replies to tweets.[171][172]
User monetization
In June 2021, the company opened applications for its premium subscription options called Super Follows. This lets eligible accounts charge $2.99, $4.99 or $9.99 per month to subscribe to the account.[173] The launch only generated about $6,000 in its first two weeks.[174] In 2023, the Super Follows feature was rebranded as simply "subscriptions", allowing users to publish exclusive long-form posts and videos for their subscribers; the pivot in marketing was reportedly intended to help compete withSubstack.[175]
In May 2021, Twitter began testing a Tip Jar feature on its iOS and Android clients. The feature allows users to send monetary tips to certain accounts, providing a financial incentive for content creators on the platform. The Tip Jar is optional and users can choose whether or not to enable tips for their account.[176] On September 23, 2021, Twitter announced that it will allow users to tip users on the social network withbitcoin. The feature will be available for iOS users. Previously, users could tip with fiat currency using services such as Square'sCash App and PayPal'sVenmo. Twitter will integrate the Strike bitcoin lightning wallet service. It was noted that at this current time, Twitter will not take a cut of any money sent through the tips feature.[177]
On August 27, 2021, Twitter rolled out Ticketed Spaces, which let Twitter Spaces hosts charge between $1 and $999 for access to their rooms.[178] In April 2022, Twitter announced that it will partner withStripe, Inc. for piloting cryptocurrency payouts for limited users in the platform. Eligible users of Ticketed Spaces and Super Follows will be able to receive their earnings in the form of USD coin, a stablecoin whose value is that of the U.S. dollar. Users can also hold their earnings in crypto wallets, and then exchange them into other cryptocurrencies.[179]
E-commerce
From 2014 to 2017, Twitter offered a "Buy button" feature, allowing tweets to embed products that could be purchased from within the service. Users could also add their billing and shipping information directly to their accounts. The buy button's platform partners at launch includedStripe,Gumroad,Musictoday, andThe Fancy.[180]
In July 2021, Twitter began testing a "Shop module" for iOS users in the United States, allowing accounts associated with brands to display a carousel of cards on their profiles showcasing products. Unlike the Buy button, where order fulfillment was handed from within Twitter, these cards are external links to online storefronts from which the products may be purchased.[181] In March 2022, Twitter expanded the test to allow companies to showcase up to 50 products on their profiles.[182] In November 2021, Twitter introduced support for "shoppable" live streams, in which brands can hold streaming events that similarly display banners and pages highlighting products that are featured in the presentation.[183]
X Money Account
In January 2025, X announced plans to introduce an "X Money Account" feature later in the year.[184] The product would be a digital wallet and enable X users to move funds between traditional bank accounts and their digital wallet and make instant peer-to-peer payments.[185]Visa was announced as partnering with X on the project and, at least initially,cryptocurrencies would not be supported.[186]
Daily user estimates vary as the company does not publish statistics on active accounts. A February 2009Compete.com blog entry ranked Twitter as the third most used social network based on their count of 6 million unique monthly visitors and 55 million monthly visits.[47] An April 2017 astatista.com blog entry ranked Twitter as the tenth most used social network based on their count of 319 million monthly visitors.[187] Its global user base in 2017 was 328 million.[188] According to Musk, the platform had 500 million monthly active users in March 2023, 550 million in March 2024, and 600 million in May 2024.[30][189][190]
In 2009, Twitter was mainly used by older adults who might not have used other social sites before Twitter.[191] According tocomScore only 11% of Twitter's users were aged 12 to 17.[191] According to a study bySysomos in June 2009, women made up a slightly larger Twitter demographic than men—53% over 47%. It also stated that 5% of users accounted for 75% of all activity.[192] According toQuantcast, 27 million people in the US used Twitter in September 2009; 63% of Twitter users were under 35 years old; 60% of Twitter users were Caucasian, but a higher than average (compared to other Internet properties) were African American/black (16%) and Hispanic (11%); 58% of Twitter users have a total household income of at least US$60,000.[193] The prevalence of African American Twitter usage and in many popular hashtags has been the subject of research studies.[194][195]
Twitter grew from 100 million monthly active users (MAUs) in September 2011,[196] to 255 million in March 2014,[197] and more than 330 million in early 2019.[198][199][60] In 2013, there were over 100 million users actively using Twitter daily and about 500 million tweets every day.[200] A 2016Pew research poll found that Twitter is used by 24% of all online US adults. It was equally popular with men and women (24% and 25% of online Americans respectively), but more popular with younger generations (36% of 18–29-year olds).[201] A 2019 survey conducted by thePew Foundation found that Twitter users are three times as likely to be younger than 50 years old, with the median age of adult U.S. users being 40. The survey found that 10% of users who are most active on Twitter are responsible for 80% of all tweets.[202]
Content
Content of tweets according to Pear Analytics in August 2009
News (3.6%)
Spam (3.8%)
Self-promotion (6%)
Pointless babble (40%)
Conversational (38%)
Pass-along value (8.7%)
San Antonio-based market-research firm Pear Analytics analyzed 2,000 tweets (originating from the United States and in English) over a two-week period in August 2009 from 11:00 am to 5:00 pm (CST) and separated them into six categories.[203]Pointless babble made up 40%, with 38% being conversational. Pass-along value had 9%, self-promotion 6% withspam and news each making 4%.
Despite Jack Dorsey's own open contention that a message on Twitter is "a short burst of inconsequential information", social networking researcherdanah boyd responded to the Pear Analytics survey by arguing that what the Pear researchers labeled "pointless babble" is better characterized as "social grooming" or "peripheral awareness" (which she justifies as persons "want[ing] to know what the people around them are thinking and doing and feeling, even when co-presence isn't viable").[204] Similarly, a survey of Twitter users found that a more specific social role of passing along messages that include a hyperlink is an expectation of reciprocal linking by followers.[205]
Levels of use
According to research published in April 2014, around 44% of user accounts have never tweeted.[206] About 22% of Americans say they have used Twitter, according to a 2019Pew Research Center survey.[207] In 2009,Nielsen Online reported that Twitter had a user-retention rate of 40%. Many people stop using the service after a month; therefore the site may potentially reach only about 10% of allInternet users.[208] Noting how demographics of Twitter users differ from the average Americans, commentators have cautioned against media narratives that treat Twitter as representative of the population,[209] adding that only 10% of users Tweet actively, and that 90% of Twitter users have Tweeted no more than twice. In 2016, shareholders sued Twitter, alleging it "artificially inflated its stock price by misleading them about user engagement". The company announced on September 20, 2021, that it would pay $809.5 million to settle this class-action lawsuit.[210]
User engagement
User engagement is usually measured by the number of likes, replies and reposts. A 2023 study showed that retweets are more likely to contain positive content and address larger audiences using the first-personpronoun "we". Replies, on the other hand, are more likely to contain negative content and address individuals using the second-person pronoun "you" and the third-person pronouns "he" or "she". While influencers with many followers tend to post positive messages, often using the word "love" when addressing larger audiences, users with less followers tend to engage ininterpersonal conversations to provoke user engagement.[211]
Branding
Before its rebranding to X, Twitter was internationally identifiable by its signature bird logo, or the Twitter Bird. The original logo, which was simply the wordTwitter, was in use from its launch in March 2006. It was accompanied by an image of a bird which was later discovered to be a piece ofclip art created by the British graphic designerSimon Oxley.[212] A new logo had to be redesigned by founder Biz Stone with help from designer Philip Pascuzzo, which resulted in a more cartoon-like bird in 2009. This version had been named "Larry the Bird" afterLarry Bird of the NBA'sBoston Celtics fame.[212][213]
Within a year, the Larry the Bird logo underwent a redesign by Stone and Pascuzzo to eliminate the cartoon features, leaving a solid silhouette of Larry the Bird that was used from 2010 through 2012.[212] In 2012, Douglas Bowman created a further simplified version of Larry the Bird, keeping the solid silhouette but making it more similar to amountain bluebird.[214] This logo was simply called the "Twitter Bird" and was used until July 2023.[212][215][216]
Twitter's profile in December 2021 (top) and X's profile in August 2023 (bottom)
On July 22, 2023, Elon Musk announced that the service would be rebranded to "X",[217] in his pursuit of creating an "everything app".[216] Musk's Twitter profile picture, along with the platform's official accounts, and the icons when browsing/signing up for the platform, were updated to reflect the new logo.[218] The logo (𝕏) is a Unicodemathematical alphanumeric symbol for the letter "X" styled indouble-strike bold.
Mike Proulx ofThe New York Times was critical of this change, saying the brand value has been "wiped out". Mike Carr says the new logo gives a"'Big Brother' tech overlord vibe" in contrast to the "cuddly" nature of the previous bird logo.[219] Usersreview bombed the newly rebranded "X" app on theiOS App Store on the day it was revealed, andRolling Stone's Miles Klee said that the rebrand "reeks of desperation".[220][221]

Finances
Revenue sources
On April 13, 2010, Twitter announced plans to offer paid advertising for companies that would be able to purchase "promoted tweets" to appear in selective search results on the Twitter website, similar toGoogle Adwords' advertising model.[222][223] Users' photos can generate royalty-free revenue for Twitter, and an agreement withWorld Entertainment News Network (WENN) was announced in May 2011.[224] Twitter generated an estimated US$139.5 million in advertising sales during 2011.[225]
In June 2011, Twitter announced that it would offer small businesses a self-service advertising system.[226] The self-service advertising platform was launched in March 2012 toAmerican Express card members and merchants in the U.S. on an invite-only basis.[227] To continue their advertising campaign, Twitter announced on March 20, 2012, that promoted tweets would be introduced to mobile devices.[228] In April 2013, Twitter announced that its Twitter Ads self-service platform, consisting of promoted tweets and promoted accounts, was available to all U.S. users without an invite.[227]
On August 3, 2016, Twitter launched Instant Unlock Card, a new feature that encourages people to tweet about a brand to earn rewards and use the social media network's conversational ads. The format itself consists of images or videos with call-to-action buttons and a customizable hashtag.[229]
In October 2019, Twitter announced it would stop running political ads on its ad platform effective November 22. This resulted from several spurious claims made by political ads. Company CEO Dorsey clarified that internet advertising had great power and was extremely effective for commercial advertisers, the power brings significant risks to politics where crucial decisions impact millions of lives.[232] The company reversed the ban in August 2023,[233] publishing criteria governing political advertising which do not allow the promotion of false or misleading content, and requiring advertisers to comply with laws, with compliance being the sole responsibility of the advertiser.[234]
In April 2022, Twitter announced a ban on "misleading" advertisements that go against "the scientific consensus on climate change". While the company did not give full guidelines, it stated that the decisions would be made with the help of "authoritative sources", including theIntergovernmental Panel on Climate Change.[235]
Fines
Twitter had been fined several times for non-compliance with laws and regulations. On May 25, 2022, Twitter was fined $150 million by theFederal Trade Commission and the United States Department of Justice for collecting users' contact details and using them for targeted advertising.[236][237]
In the early days of Twitter, tweets were stored inMySQL databases that were temporallysharded (large databases were split based on time of posting). After the huge volume of tweets coming in caused problems reading from and writing to these databases, the company decided that the system needed re-engineering.[241]
From Spring 2007 to 2008, the messages were handled by a Rubypersistent queue server called Starling.[242] Since 2009, implementation has been gradually replaced with software written inScala.[243] The switch from Ruby to Scala and theJVM has given Twitter a performance boost from 200 to 300 requests per second per host to around 10,000–20,000 requests per second per host. This boost was greater than the 10x improvement that Twitter's engineers envisioned when starting the switch. The continued development of Twitter has also involved a switch from monolithic development of a single app to an architecture where different services are built independently and joined throughremote procedure calls.[241]
As of April 6, 2011, Twitter engineers confirmed that they had switched away from their Ruby on Rails search stack to aJava server they call Blender.[244] Individual tweets are registered under unique IDs calledsnowflakes, and geolocation data is added using 'Rockdove'. The URL shortenert.co then checks for aspam link and shortens the URL. Next, the tweets are stored in a MySQL database usingGizzard, and the user receives an acknowledgement that the tweets were sent. Tweets are then sent to search engines via the Firehose API. The process is managed byFlockDB and takes an average of350 ms.[238]
On August 16, 2013,Raffi Krikorian, Twitter's vice president of platform engineering, shared in a blog post that the company's infrastructure handled almost 143,000 tweets per second during that week, setting a new record. Krikorian explained that Twitter achieved this record by blending its homegrown and open source technologies.[241][245]
X Money, a payment system, is under development.[246]
API and developer platform
Twitter was recognized for having one of the most open and powerful developerAPIs of any major technology company.[247] The service's API allows otherweb services and applications to integrate with Twitter.[248] Developer interest in Twitter began immediately following its launch, prompting the company to release the first version of its public API in September 2006.[249] The API quickly became iconic as a reference implementation for publicREST APIs and is widely cited in programming tutorials.[250]
From 2006 until 2010, Twitter's developer platform experienced strong growth and a highly favorable reputation. Developers built upon the public API to create the first Twitter mobile phone clients as well as the first URL shortener. Between 2010 and 2012, however, Twitter made a number of decisions that were received unfavorably by the developer community.[251] In 2010, Twitter mandated that all developers adoptOAuth authentication with just 9 weeks of notice.[252] Later that year, Twitter launched its own URL shortener, in direct competition with some of its most well-known third-party developers.[253] And in 2012, Twitter introduced stricter usage limits for its API, "completely crippling" some developers.[254][255] While these moves successfully increased the stability and security of the service, they were broadly perceived as hostile to developers, causing them to lose trust in the platform.[256]
In July 2020, Twitter released version 2.0 of the public API[257] and began showcasing Twitter apps made by third-party developers on its Twitter Toolbox section in April 2022.[258]
In January 2023, Twitter ended third-party access to its APIs, forcing all third-party Twitter clients to shut down.[259] This was controversial among the developer community, as many third-party apps predated the company's official apps, and the change was not announced beforehand. Twitterrific's Sean Heber confirmed in a blog post that the 16-year-old app has been discontinued. "We are sorry to say that the app's sudden and undignified demise is due to an unannounced and undocumented policy change by an increasingly capricious Twitter – a Twitter that we no longer recognize as trustworthy nor want to work with any longer."[260] In February 2023, Twitter announced it would be ending free access to Twitter API, and began offering paid tier plans with a more limited access.[261]
Innovator's patent agreement
On April 17, 2012, Twitter announced it would implement an "Innovators Patent Agreement" which would obligate Twitter to only use its patentsfor defensive purposes.[clarify][262]
Open source
Twitter has a history of both using and releasingopen-source software while overcoming technical challenges of their service.[263] A page in their developer documentation thanks dozens of open-source projects which they have used, fromrevision control software likeGit to programming languages such as Ruby and Scala.[264] Software released as open source by the company includes theGizzard Scala framework for creating distributed datastores, the distributed graph databaseFlockDB, the Finagle library for building asynchronousRPC servers and clients, the TwUIuser interface framework foriOS, and the Bower client-side package manager.[265] The popularBootstrap frontend framework was also started at Twitter and is 10th most popular repository onGitHub.[266]
On March 31, 2023, Twitter released thesource code for Twitter's recommendationalgorithm,[267] which determines what tweets show up on the user's personal timeline, toGitHub. According to Twitter's blog post: "We believe that we have a responsibility, as the town square of the internet, to make our platform transparent. So today we are taking the first step in a new era of transparency and opening much of our source code to the global community."[268]Elon Musk, the CEO at the time, had been promising the move for a while – on March 24, 2022, before he owned the site, he polled his followers about whether Twitter's algorithm should be open source, and around 83% of the responses said "yes". In February, he promised it would happen within a week before pushing back the deadline to March 31 earlier this month.[269]
Also in March 2023, Twitter suffered a security attack which resulted in proprietary code being released. Twitter then had the source code removed.[270]
Interface
Twitter introduced the first major redesign of its user interface in September 2010, adopting a dual-pane layout with a navigation bar along the top of the screen, and an increased focus on the inline embedding of multimedia content. Critics considered the redesign an attempt to emulate features and experiences found in mobile apps and third-party Twitter clients.[271][272][273][274]
The new layout was revised in 2011 with a focus on continuity with the web and mobile versions, introducing "Connect" (interactions with other users such as replies) and "Discover" (further information regarding trending topics and news headlines) tabs, an updated profile design, and moving all content to the right pane (leaving the left pane dedicated to functions and the trending topics list).[275] In March 2012, Twitter became available in Arabic,Farsi,Hebrew andUrdu, the first right-to-left language versions of the site.[276] In 2023 the Twitter Web site listed 34 languages supported by Twitter.com.[277]
In September 2012, a new layout for profiles was introduced, with larger "covers" that could be customized with a custom header image, and a display of the user's recent photos posted.[278] The "Discover" tab was discontinued in April 2015,[279] and was succeeded on the mobile app by an "Explore" tab—which features trending topics and moments.[280] In September 2018, Twitter began to migrate selected web users to itsprogressive web app (based on its Twitter Lite experience for mobile web), reducing the interface to two columns. Migrations to this iteration of Twitter increased in April 2019, with some users receiving it with a modified layout.[281][282]
In July 2019, Twitter officially released this redesign, with no further option to opt-out while logged in. It is designed to further-unify Twitter's user experience between the web andmobile application versions, adopting a three-column layout with a sidebar containing links to common areas (including "Explore" that has been merged with the search page) which previously appeared in a horizontal top bar, profile elements such as picture and header images and biography texts merged into the same column as the timeline, and features from the mobile version (such as multi-account support, and an opt-out for the "top tweets" mode on the timeline).[283][284]
Security
In response to early Twitter security breaches, the United StatesFederal Trade Commission (FTC) brought charges against the service; the charges were settled on June 24, 2010. This was the first time the FTC had taken action against a social network for security lapses. The settlement requires Twitter to take a number of steps to secure users' private information, including maintenance of a "comprehensive information security program" to be independently audited biannually.[285] After a number of high-profile hacks of official accounts, including those of theAssociated Press andThe Guardian,[286] in April 2013, Twitter announced a two-factor login verification as an added measure against hacking.[287]
On July 15, 2020, amajor hack of Twitter affected 130 high-profile accounts, both verified and unverified ones such asBarack Obama,Bill Gates, andElon Musk; the hack allowedbitcoin scammers to send tweets via the compromised accounts that asked the followers to send bitcoin to a given public address, with the promise to double their money.[288] Within a few hours, Twitter disabled tweeting and reset passwords from all verified accounts.[288] Analysis of the event revealed that the scammers had usedsocial engineering to obtain credentials from Twitter employees to access an administration tool used by Twitter to view and change these accounts' personal details as to gain access as part of a "smash and grab" attempt to make money quickly, with an estimatedUS$120,000 in bitcoin deposited in various accounts before Twitter intervened.[289] Several law enforcement entities including the FBI launched investigations into the attack.[290]
On August 5, 2022, Twitter disclosed that a bug introduced in a June 2021 update to the service allowed threat actors to link email addresses and phone numbers to twitter user's accounts.[291][292] The bug was reported through Twitter'sbug bounty program in January 2022 and subsequently fixed. While Twitter originally believed no one had taken advantage of the vulnerability, it was later revealed that a user on the online hacking forumBreach Forums had used the vulnerability to compile a list of over 5.4 million user profiles, which they offered to sell for $30,000.[293][294] The information compiled by the hacker includes user's screen names, location and email addresses which could be used inphishing attacks or used to deanonymize accounts running under pseudonyms.
Outages
During an outage, Twitter users were at one time shown the "fail whale"error message image created byYiying Lu,[295] illustrating eight orange birds using a net to hoist a whale from the ocean captioned "Too many tweets! Please wait a moment and try again."[296] Web designer and Twitter userJen Simmons was the first to coin the term "fail whale" in a September 2007 tweet.[297][298] In a November 2013Wired interview Chris Fry, VP of Engineering at that time, noted that the company had taken the "fail whale" out of use as the platform was now more stable.[299] Twitter had approximately 98%uptime in 2007 (or about six full days of downtime).[300] The downtime was particularly noticeable during events popular with the technology industry such as the 2008Macworld Conference & Expo keynote address.[301][302]
In June 2009, after being criticized byKanye West and sued byTony La Russa over unauthorized accounts run byimpersonators, the company launched their "Verified Accounts" program.[303][304] Twitter stated that an account with a "blue tick" verification badge indicates "we've been in contact with the person or entity the account is representing and verified that it is approved".[305] In July 2016, Twitter announced a public application process to grant verified status to an account "if it is determined to be of public interest" and that verification "does not imply an endorsement".[306][307][308] Verified status allows access to some features unavailable to other users, such as only seeing mentions from other verified accounts.[309]
In November 2020, Twitter announced a relaunch of its verification system in 2021. According to the new policy, Twitter verifies six different types of accounts; for three of them (companies, brands, and influential individuals like activists), the existence of a Wikipedia page will be one criterion for showing that the account has "Off Twitter Notability".[310] Twitter states that it will re-open public verification applications at some point in "early 2021".[311]
In October 2022, after the takeover of Twitter by Elon Musk, it was reported that verification would instead be included in the paid Twitter Blue service, and that existing verified accounts would lose their status if they do not subscribe.[312] On November 1, Musk confirmed that verification would be included in Blue in the future, dismissing the existing verification system as a "lords & peasants system".[157][158][159] After concerns over the possibility of impersonation, Twitter subsequently reimplemented a second "Official" marker, consisting of a grey tick and "Official" text displayed under the username, for high-profile accounts of "government and commercial entities".[313][314] In December 2022, the "Official" text was replaced by a gold checkmark for organizations, as well as a grey check mark for government and multilateral accounts.[315][316]
In March 2023, the gold check mark was made available for organizations to purchase through the Verified Organizations program (formerly called Twitter Blue for Business).[315][316]
Privacy
Tweets are public, but users can also send private "direct messages".[317] Information about who has chosen to follow an account and who a user has chosen to follow is also public, though accounts can be changed to "protected" which limits this information (and all tweets) to approved followers.[318] Twitter collectspersonally identifiable information about its users and shares it with third parties as specified in itsprivacy policy. The service also reserves the right to sell this information as an asset if the company changes hands.[319][non-primary source needed][320] Advertisers cantarget users based on their history of tweets and may quote tweets in ads[321] directed specifically to the user.
Twitter launched thebeta version of their "Verified Accounts" service on June 11, 2009, allowing people with public profiles to announce their account name. The profile pages of these accounts display a badge indicating their status.[322] On December 14, 2010, theUnited States Department of Justice issued asubpoena directing Twitter to provide information for accounts registered to or associated withWikiLeaks.[323] Twitter decided to notify its users and said, "... it's our policy to notify users about law enforcement and governmental requests for their information, unless we are prevented by law from doing so."[317]
In May 2011, aclaimant known as "CTB" in the case ofCTB v Twitter Inc. took action against Twitter at theHigh Court of Justice of England and Wales,[324] requesting that the company release details of account holders. This followed gossip posted on Twitter about professional footballerRyan Giggs's private life. This led to the2011 British privacy injunctions controversy and the "super-injunction".[325] Tony Wang, the head of Twitter in Europe, said that people who do "bad things" on the site would need to defend themselves under the laws of their own jurisdiction in the event of controversy and that the site would hand over information about users to the authorities when it was legally required to do so.[326] He also suggested that Twitter would accede to a UK court order to divulge names of users responsible for "illegal activity" on the site.[327]
Twitter acquiredDasient, a startup that offers malware protection for businesses, in January 2012. Twitter announced plans to use Dasient to help remove hateful advertisers on the website.[328] Twitter also offered a feature which would allow tweets to be removed selectively by country, before deleted tweets used to be removed in all countries.[329][330] The first use of the policy was to block the account of Germanneo-Nazi groupBesseres Hannover on October 18, 2012.[331] The policy was used again the following day to removeanti-Semitic French tweets with the hashtag #unbonjuif ("a good Jew").[332] After the sharing of images showing the killing of American journalistJames Foley in 2014, Twitter said that in certain cases it would delete pictures of people who had died after requests from family members and "authorized individuals".[333][334]
In 2015, following updated terms of service and privacy policy, Twitter users outside the United States were legally served by the Ireland-based Twitter International Company instead of Twitter, Inc. The change made these users subject to Irish andEuropean Union data protection laws.[335] On April 8, 2020, Twitter announced that users outside of the European Economic Area or United Kingdom (thus subject to GDPR) will no longer be allowed to opt out of sharing "mobile app advertising measurements" to Twitter third-party partners.[336]
On October 9, 2020, Twitter took additional steps to counter misleading campaigns ahead of the 2020 US Election. Twitter's new temporary update encouraged users to "add their own commentary" before retweeting a tweet, by making 'quoting tweet' a mandatory feature instead of optional. The social network giant aimed at generating context and encouraging the circulation of more thoughtful content.[337] After limited results, the company ended this experiment in December 2020.[338]
On May 25, 2022, Twitter was fined $150 million for collecting users' phone numbers and email addresses used forsecurity and using them fortargeted advertising, required to notify its users, and banned from profiting from "deceptively collected data".[339] TheFederal Trade Commission (FTC) and theDepartment of Justice stated that Twitter violated a 2011 agreement not to use personal security data for targeted advertising.
In September 2024, the FTC released a report summarizing 9 company responses (including from Twitter) to orders made by the agency pursuant to Section 6(b) of theFederal Trade Commission Act of 1914 to provide information about user and non-user data collection (including of children and teenagers) and data use by the companies that found that the companies' user and non-user data practices put individuals vulnerable toidentity theft,stalking, unlawful discrimination, emotional distress andmental health issues, social stigma, and reputational harm.[340][341][342]
Harassment
In August 2013, Twitter announced plans to introduce a "report abuse" button for all versions of the site following uproar, including a petition with 100,000 signatures, over Tweets that included rape and death threats to historianMary Beard, feminist campaignerCaroline Criado-Perez and the member of parliamentStella Creasy.[343][344][345] Twitter announced new reporting and blocking policies in December 2014,[346][347][348][349] including a blocking mechanism devised byRandi Harper, a target ofGamerGate.[350][351][352] In February 2015, CEODick Costolo said he was 'frankly ashamed' at how poorly Twitter handledtrolling and abuse, and admitted Twitter had lost users as a result.[353] As per a research study conducted by IT for Change on abuse and misogynistic trolling on Twitter directed at Indian women in public-political life, women perceived to be ideologically left-leaning, dissenters, Muslim women, political dissenters, and political commentators and women from opposition parties received a disproportionate amount of abusive and hateful messages on Twitter.[354]
In 2016, Twitter announced the creation of the Twitter Trust & Safety Council to help "ensure that people feel safe expressing themselves on Twitter". The council's inaugural members included 50 organizations and individuals.[355] The announcement of Twitter's "Trust & Safety Council" was met with objection from parts of its userbase.[356][357] Critics accused the member organizations of being heavily skewed towards "the restriction of hate speech" and aReason article expressed concern that "there's not a single uncompromising anti-censorship figure or group on the list".[358][359]
Twitter banned 7,000 accounts and limited 150,000 more that had ties toQAnon on July 21, 2020. The bans and limits came after QAnon-related accounts began harassing other users through practices of swarming or brigading, coordinated attacks on these individuals through multiple accounts in the weeks prior. Those accounts limited by Twitter will not appear in searches nor be promoted in other Twitter functions. Twitter said they will continue to ban or limit accounts as necessary, with their support account stating "We will permanently suspend accounts Tweeting about these topics that we know are engaged in violations of our multi-account policy, coordinating abuse around individual victims, or are attempting to evade a previous suspension".[360]
In September 2021, Twitter began beta testing a feature called Safety Mode.[361] The functionality aims to limit unwelcome interactions through automated detection of negative engagements. If a user has Safety Mode enabled, authors of tweets that are identified by Twitter's technology as being harmful or exercising uninvited behavior will be temporarily unable to follow the account, send direct messages, or see tweets from the user with the enabled functionality during the temporary block period.[362] Jarrod Doherty, senior product manager at Twitter, stated that the technology in place within Safety Mode assesses existing relationships to prevent blocking accounts that the user frequently interacts with.[361]
In January 2016, Twitter was sued by the widow of a U.S. man killed in the2015 Amman shooting attack, claiming that allowing theIslamic State of Iraq and the Levant (ISIL) to continually use the platform, including direct messages in particular,[363] constituted theprovision of material support to a terrorist organization, which is illegal under U.S. federal law. Twitter disputed the claim, stating that "violent threats and the promotion of terrorism deserve no place on Twitter and, like other social networks, our rules make that clear".[364][365] The lawsuit was dismissed by theUnited States District Court for the Northern District of California, upholding theSection 230 safe harbor, which dictates that the operators of an interactive computer service are not liable for the content published by its users.[365][366] The lawsuit was revised in August 2016, providing comparisons to other telecommunications devices.[363] The second amended complaint was dismissed by the district court, a decision affirmed on appeal to the U.S. Court of Appeals for the Ninth Circuit on January 31, 2018.[367]
Twitter suspended multiple parody accounts that satirized Russian politics in May 2016, sparking protests and raising questions about where the company stands onfreedom of speech.[368] Following public outcry, Twitter restored the accounts the next day without explaining why the accounts had been suspended.[369] The same day, Twitter, along with Facebook, Google, andMicrosoft, jointly agreed to aEuropean Union code of conduct obligating them to review "[the] majority of valid notifications for removal of illegalhate speech" posted on their services within 24 hours.[370] In August 2016, Twitter stated that it had banned 235,000 accounts over the past six months, bringing the overall number of suspended accounts to 360,000 accounts in the past year, for violating policies banning use of the platform to promote extremism.[371] On May 10, 2019, Twitter announced that they suspended 166,513 accounts for promoting terrorism in the July–December 2018 period, saying there was a steady decrease in terrorist groups trying to use the platform owing to its "zero-tolerance policy enforcement". According toVijaya Gadde, Legal, Policy and Trust and Safety Lead at Twitter, there was a reduction of 19% terror related tweets from the previous reporting period (January–June 2018).[372][373][374][375][376]
As of July 30, 2020, Twitter will block URLs in tweets that point to external websites that contain malicious content (such as malware and phishing content) as well as hate speech, speech encouraging violence, terrorism, child sexual exploitation, breaches of privacy, and other similar content that is already banned as part of the content of tweets on the site. Users that frequently point to such sites may have their accounts suspended. Twitter said this was to bring their policy in line to prevent users from bypassing their tweet content restrictions by simply linking to the banned content.[377]
After the onset of protests byDonald Trump's supporters across the US in January 2021, Twitter suspended more than 70,000 accounts, stating that they shared "harmfulQAnon-associated content" at a large scale, and were "dedicated to the propagation of this conspiracy theory across the service".[378] One of the accounts suspended was then-former-president Trump's account; in February 2025, Twitter settled a lawsuit filed by Trump in response to his suspension paying Trump approximately $10 million.[379]
Malicious and fake accounts
Between January and late July 2017, Twitter had identified and shut down over 7,000 fake accounts created by Iranian influence operations.[380]
In May 2018, in response to scrutiny over the misuse of Twitter by those seeking to maliciously influence elections, Twitter announced that it would partner with the nonprofit organizationBallotpedia to add special labels verifying the authenticity of political candidates running for election in the U.S.[381][382] In December 2019, Twitter removed 5,929 accounts for violating theirmanipulation policies. The company investigated and attributed these accounts to a single state-run information operation, which originated in Saudi Arabia. The accounts were reported to be a part of a larger group of 88,000 accounts engaged inspammy behavior. However, Twitter did not disclose all of them as some could possibly be legitimate accounts taken over throughhacking.[383]
In March 2021, Twitter suspended around 3,500 fake accounts that were running a campaign to influence the American audience, after the US intelligence officials concluded that the assassination ofThe Washington Post journalistJamal Khashoggi was "approved" by the Saudi Crown PrinceMohammed bin Salman. These Saudi accounts were working in two languages, English and Arabic, to influence public opinion around the issue. Many accounts commented directly on the tweets of US-based media houses, includingThe Post,CNN,CBS News andThe Los Angeles Times. Twitter was unable to identify the source of the influence campaign.[384]
As of 2022[update], the top four countries spreading state-linked Twitter misinformation are Russia, China, Iran and Saudi Arabia.[385]
A bot is a computer program that can automatically tweet, retweet, and follow other accounts. Twitter's openapplication programming interface and the availability of cloud servers make it possible for bots to exist within the social networking site.[386] Benign bots may generate creative content and relevant product updates, whereas malicious bots can make unpopular people seem popular, push irrelevant products on users, and spread misinformation, spam or slander.[387] Bots amass significant influence and have been noted to sway elections, influence the stock market, appeal to the public, and attack governments.[388] As of 2013[update], Twitter said there were 20 million fake accounts on Twitter, representing less than 5% of active users.[389] A 2020 estimate put the figure at 15% of all accounts or around 48 million accounts.[15]
This section should include only abrief summary ofTwitter usage. SeeWikipedia:Summary style for information on how to properly incorporate it into this article's main text.(November 2023)
The service was also used as a form ofcivil disobedience: In 2010, users expressed outrage over theTwitter joke trial by copying a controversial joke about bombing an airport and attaching the hashtag #IAmSpartacus, a reference to the filmSpartacus (1960) and a sign of solidarity and support to a man controversially prosecuted after posting a tweet joking about bombingan airport if they canceled his flight. #IAmSpartacus became the number one trending topic on Twitter worldwide.[392] Another case of civil disobedience happened in the2011 British privacy injunction debate, where several celebrities who had taken out anonymized injunctions were identified by thousands of users in protest to traditional journalism being censored.[393]
Governments
According to documents leaked byEdward Snowden and published in July 2014, the United Kingdom'sGCHQ has a tool named BIRDSONG for "automated posting of Twitter updates" and a tool named BIRDSTRIKE for "Twitter monitoring and profile collection".[394][395]
On June 12, 2020, Twitter suspended over 7,000 accounts from Turkey because those accounts were fake profiles, designed to support the Turkish president,Recep Tayyip Erdoğan, and were managed by a central authority. Turkey's communication director said that the decision was illogical, biased, and politically motivated.[401] Turkey blocked access to Twitter twice, once after voice recordings appeared on Twitter in which Erdoğan ordered his son to stash away millions of dollars and another time for 12 hours in the aftermath of theearthquake of February 2023, when Erdoğan blamed the people for a disinformation campaign as they criticized the Government for their lack of help.[402] In May 2021, Twitter labeled one of the tweets bySambit Patra, a spokesman of the local ruling partyBJP in India, as "manipulated media", leading to Twitter's offices in Delhi andGurgaon being raided by the local police.[403] Later, theIndian government released a statement in July 2021 claiming Twitter has lost its liability protection concerning user-generated content. This was brought on by Twitter's failure to comply with thenew IT rules introduced in 2021, with a filing stating that the company failed to appoint executives to govern user content on the platform.[404] In 2025, Twitter sued the Indian government for using the IT Act to block tweets and other content on its platform.[405]
According to a report byReuters, the United States ran apropaganda campaign to spread disinformation about theSinovac Chinese COVID-19 vaccine, including using fake social media accounts on Twitter to spread the disinformation that the Sinovac vaccine contained pork-derived ingredients and was thereforeharam underIslamic law.[406] The campaign primarily targeted people in the Philippines and used a social media hashtag for "China is the virus" inTagalog.[406]
Pornographic content
Twitter allows pornographic content as long as it is marked "sensitive" by uploaders, which puts it behind an interstice and hides it from minors.[407] The "super-follow" feature is said to enable competition with the subscription siteOnlyFans, used mainly by sex workers.[408] Many performers use Twitter's service to market and grow their porn businesses, attracting users to paywalled services like OnlyFans by distributing photos and short video clips as advertisements.[409][410]
In April 2022, Twitter convened a "Red Team" for the project of ACM, "Adult Content Monetization", as it is known internally. Eventually, the project was abandoned, because of the difficulty of implementing Real ID.[411]
Child sexual exploitation
A February 2021 report from the company's Health team begins, "While the amount of CSE (child sexual exploitation) online has grown exponentially, Twitter's investment in technologies to detect and manage the growth has not."[411]
Until February 2022, the only way for users to flag illegal content was to flag it as "sensitive media", a broad category that left much of the worst material unprioritized for moderation. In a February report, employees wrote that Twitter, along with other Tech Companies have "accelerated the pace of CSE content creation and distribution to a breaking point where manual detection, review, and investigations no longer scale" by allowing pornography and failing to invest in systems that could effectively monitor it. The working group made several recommendations, but they were not taken up and the group was disbanded.[411] As part of its efforts to monetize porn, Twitter held an internal investigation which reported in April 2022, "Twitter cannot accurately detect child sexual exploitation and non-consensual nudity at scale."[411]
John Doe et al. v. Twitter, a civil lawsuit filed in the 9th Circuit Court, alleges that Twitter benefited from sex trafficking and refused to remove the illegal tweets when first informed of them.[412][413] In an amicus brief filed in the case, theNCMEC said, "The children informed the company that they were minors, that they had been 'baited, harassed, and threatened' into making the videos, that they were victims of 'sex abuse' under investigation by law enforcement" but Twitter failed to remove the videos, "allowing them to be viewed by hundreds of thousands of the platform's users".[411]
Some major brands, includingDyson,Mazda,Forbes, andPBS Kids suspended their marketing campaigns and pulled their ads from the platform after an investigation showed that Twitter failed to suspend 70% of the accounts that shared or solicited the prohibited content.[414]
Impact
This sectionmay betoo long and excessively detailed. Please consider summarizing the material.(May 2022)
Emergency use
A practical use for Twitter's real-time functionality is as an effectivede facto emergency communication system for breaking news. It was neither intended nor designed for high-performance communication, but the idea that it could be used for emergency communication was not lost on the creators, who knew that the service could have wide-reaching effects early on when the company used it to communicate during earthquakes.[415]Another practical use that is being studied is Twitter's ability to track epidemics and how they spread.[416] Additionally Twitter serves as a real-time sensor for natural disasters such as bushfires and earthquakes.[417][418]
Education
Twitter has been adopted as a communication and learning tool in educational and research[419] settings mostly in colleges and universities.[420][421] It has been used as abackchannel to promote student interactions, especially in large-lecture courses.[422] Research has found that using Twitter in college courses helps students communicate with each other and faculty, promotes informal learning, allows shy students a forum for increased participation, increases student engagement, and improves overall course grades.[423][424][425]
Twitter has been an increasingly growing in the field of education as an effective tool that can be used to encourage learning and idea, or knowledge sharing, in and outside the classroom.[426] By using or creating hashtags, students and educators are able to communicate under specific categories of their choice to enhance and promote education. A broad example of a hashtag used in education is "edchat", to communicate with other teachers and people using that hashtag. Once teachers find someone they want to talk to, they can either direct message the person or narrow down the hashtag to make the topic of the conversation more specific, using hashtags for scichat (science), engchat (English), sschat (social studies).[426]
Public figures
Jonathan Zittrain, professor of Internet law atHarvard Law School, said that "the qualities that make Twitter seem inane and half-baked are what makes it so powerful."[427] In that same vein, and with Sigmund Freud in mind, political communications expert Matthew Auer observed that well-crafted tweets by public figures often deliberately mix trivial and serious information so as to appeal to all three parts of the reader's personality: the id, ego, and superego.[428] The poetsMira Gonzalez andTao Lin published a book titledSelected Tweets featuring selections of their tweets over some eight years.[429] The novelistRick Moody wrote a short story for Electric Literature called "Some Contemporary Characters", composed entirely of tweets.[430]
Many commentators have suggested that Twitter radically changed the format of reporting due to instant, short, and frequent communication.[431][432] According toThe Atlantic writers Benjamin M. Reilly and Robinson Meyer, Twitter has an outsized impact on the public discourse and media. "Something happens on Twitter; celebrities, politicians and journalists talk about it, and it's circulated to a wider audience by Twitter's algorithms; journalists write about the dustup." This can lead to an argument on a Twitter feed looking like a "debate roiling the country... regular people are left with a confused, agitated view of our current political discourse".[433] In a 2018 article in theColumbia Journalism Review, Matthew Ingram argued much the same about Twitter's "oversized role" and that it promotes immediacy over newsworthiness.[434] In some cases, inauthentic and provocative tweets were taken up as common opinion in mainstream articles. Writers in several outlets unintentionally cited the opinions of RussianInternet Research Agency-affiliated accounts.[434][435]
World leaders
Donald Trump's Twitter post from July 2017
World leaders and their diplomats have taken note of Twitter's rapid expansion and have been increasingly usingTwitter diplomacy, the use of Twitter to engage with foreign publics and their own citizens. US Ambassador to Russia,Michael A. McFaul has been attributed as a pioneer of international Twitter diplomacy. He used Twitter after becoming ambassador in 2011, posting in English and Russian.[436] On October 24, 2014,Queen Elizabeth II sent her first tweet to mark the opening of theLondon Science Museum's Information Age exhibition.[437] A 2013 study by website Twiplomacy found that 153 of the 193 countries represented at the United Nations had established government Twitter accounts.[438] The same study also found that those accounts amounted to 505 Twitter handles used by world leaders and their foreign ministers, with their tweets able to reach a combined audience of over 106 million followers.[438]
According to an analysis of accounts, the heads of state of 125 countries and 139 other leading politicians have Twitter accounts that have between them sent more than 350,000 tweets and have almost 52 million followers. However, only 30 of these do their own tweeting, more than 80 do not subscribe to other politicians and many do not follow any accounts.[439]
The Twitter account for the pope was set up in 2012. As of February 2025[update], it has 18 million followers (@Pontifex).[440]
Twitter is banned completely in Russia,[441] Iran, China and North Korea[442] and has been intermittently blocked in numerous countries, including Egypt, Iraq, Nigeria, Turkey, Venezuela and Turkmenistan on different basis.[443][444][445][446][447][448][449] In 2016, Twitter cooperated with the Israeli government to remove certain content originating outside Israel from tweets seen in Israel.[450] In the 11th biannual transparency report published on September 19, 2017, Twitter said that Turkey was the first among countries where about 90% of removal requests came from, followed by Russia, France and Germany.[451] Twitter stated that between July 1 and December 31, 2018, "We received legal demands relating to 27,283 accounts from 47 different countries, including Bulgaria, Kyrgyzstan, Macedonia, and Slovenia for the first time."[452] As part of evidence to a U.S. Senate Enquiry, the company admitted that their systems "detected and hid" several hundred thousand tweets relating to the2016 Democratic National Committee email leak.[453] During the curfew inJammu and Kashmir afterrevocation of its autonomous status on August 5, 2019, the Indian government approached Twitter to block accounts accused of spreading anti-India content;[454] by October 25, nearly one million tweets had been removed as a result.[455]
In March 2022, shortly afterRussia's censorship of Twitter, a Toronion service link was created by the platform to allow people to access the website, even in countries with heavy Internet censorship.[456][457]
Moderation of tweets
Twitter removed more than 88,000 propaganda accounts linked to Saudi Arabia.[458] Twitter removed tweets from accounts associated with the RussianInternet Research Agency that had tried to influence public opinion during and after the 2016 US election.[434][435] In June 2020, Twitter also removed 175,000 propaganda accounts that were spreading biased political narratives for theChinese Communist Party, theUnited Russia Party, or Turkey's PresidentErdogan, identified based on centralized behavior.[459][460] Twitter also removed accounts linked to the governments of Armenia, Egypt, Cuba, Serbia, Honduras, Indonesia and Iran.[461][462][463] Twitter suspended Pakistani accounts tied to government officials for posting tweets about theKashmir conflict between India and Pakistan.[464] In February 2021, Twitter removed accounts in India that criticized Prime MinisterNarendra Modi's government for its conduct duringIndian farmers' protests in 2020–2021.[465]
At the start of the 2020 COVID-19 pandemic, numerous tweets reported false medical information related to the pandemic. Twitter announced a new policy in which they would label tweets containing misinformation going forward.[63] In April 2020, Twitter removed accounts which defended PresidentRodrigo Duterte's response to the spread of COVID-19 in the Philippines.[466] In November 2020, then Chief Technology Officer and future CEO of TwitterParag Agrawal, when asked byMIT Technology Review about balancing the protection offree speech as a core value and the endeavour to combat misinformation, said: "Our role is not to be bound by theFirst Amendment, but our role is to serve a healthy public conversation ... focus less on thinking about free speech, but thinking about how the times have changed."[467]
Musk had been critical of Twitter's moderation of misinformation prior to his acquisition of the company.[468] After the transition, Musk eliminated the misinformation moderation team,[469] and stopped enforcing its policy on labeling tweets with misleading information about coronavirus.[470] While Twitter had joined a voluntary program under the European Union's to fight disinformation in June 2022, Musk pulled the company out of the program in May 2023.[471]
In August 2020, development of Birdwatch was announced, initially described as a moderation tool. Twitter first launched the Birdwatch program in January 2021, intended as a way to debunk misinformation and propaganda, with apilot program of 1,000 contributors,[472][473] weeks after theJanuary 6 United States Capitol attack.[474] The aim was to "build Birdwatch in the open, and have it shaped by the Twitter community". In November 2021, Twitter updated the Birdwatch moderation tool to limit the visibility of contributors' identities by creating aliases for their accounts, in an attempt to limit bias towards the author of notes.[473][475]
Twitter then expanded access to notes made by the Birdwatch contributors in March 2022, giving a randomized set of US users the ability to view notes attached to tweets and rate them,[476] with a pilot of 10,000 contributors.[477] On average, contributors were noting 43 times a day in 2022 prior to theRussian invasion of Ukraine. This then increased to 156 on the day of the invasion, estimated to be a very small portion of the misleading posts on the platform. By March 1, only 359 of 10,000 contributors had proposed notes in 2022, while a Twitter spokeswoman described plans to scale up the program, with the focus on "ensuring that Birdwatch is something people find helpful and can help inform understanding".[478][479]
By September 2022, the program had expanded to 15,000 users.[480] In October 2022, the most commonly published notes were related toCOVID-19 misinformation based on historical usage.[481] In November 2022, at the request ofnew owner Elon Musk, Birdwatch was rebranded toCommunity Notes, taking anopen-source approach to deal with misinformation,[482] and expanded to Europe and countries outside of the US.[483][484][485]
Court cases, lawsuits, and adjudication
Twitter Inc. v. Taamneh, alongsideGonzalez v. Google, were heard by theUnited States Supreme Court during its 2022–2023 term. Both cases dealt with Internet content providers and whether they are liable for terrorism-related information posted by their users. In the case ofTwitter v. Taamneh, the case asked if Twitter and other social media services are liable foruser-generated terrorism content under theAntiterrorism and Effective Death Penalty Act of 1996 and are beyond theirSection 230 protections. The court ruled in May 2023 that the charges brought against Twitter and other companies were not permissible under the Antiterrorism Act, and did not address the Section 230 question. This decision also supported the Court'sper curiam decision inGonzalez returning that case to the lower court for review in light of theTwitter decision.[486][487]
In 2016, Twitter shareholder Doris Shenwick filed a lawsuit against Twitter, Inc., claiming executives misled investors over the company's growth prospects.[488] In 2021, Twitter agreed to pay $809.5 million to settle.[488]
In May 2022, Twitter agreed to pay $150 million to settle a lawsuit started by the Department of Justice and the Federal Trade Commission. The lawsuit concerned Twitter's use of email addresses and phone numbers of Twitter users totarget advertisements at them. The company also agreed to third-party audits of itsdata privacy program.[489] On November 3, 2022, on the eve of expected layoffs, a group of Twitter employees based in San Francisco and Cambridge filed a lawsuit in the U.S. District Court in San Francisco. Naming five current or former workers as plaintiffs, the suit accused the company of violating federal and state laws that govern notice of employment termination.[490] The federal law in question is theWorker Adjustment and Retraining Notification (WARN) Act, and the state law in question is California's state WARN Act.[491]
On November 20, 2023, Twitter filed a lawsuit againstMedia Matters, a media watchdog group. The lawsuit alleges defamation by Media Matters following its publication of a report claiming that advertisements for major brands were displayed alongside posts promotingAdolf Hitler and theNazi Party.[492]
On August 6, 2024, X filed anantitrust lawsuit in theNorthern District of Texas against theWorld Federation of Advertisers,Unilever,Mars,CVS andØrsted, alleging that the advertisers had conspired via their participation in the Global Alliance for Responsible Media to withhold "billions of dollars in advertising revenue" from the platform.[493] The World Federation Of Advertisers created the Global Alliance for Responsible Media in 2019 to address "illegal or harmful content on digital media platforms and its monetization via advertising".[494] On August 13, 2024, theWorkplace Relations Commission ordered Twitter to pay €550,000 to former senior staffer Gary Rooney in an unfair dismissal case. Twitter had argued that Rooney's failure to check "yes" at the bottom of an email from Elon Musk constituted resignation.[495][496]
Aselfie orchestrated by86th Academy Awards hostEllen DeGeneres during the March 2, 2014, broadcast was, at the time, the most retweeted image ever.[497] The photo of twelve celebrities broke the previous retweet record within forty minutes and was retweeted over 1.8 million times in the first hour.[498][499][500] On May 9, 2017, Ellen's record was broken by Carter Wilkerson (@carterjwm) by collecting nearly 3.5 million retweets in a little over a month.[501] This record was broken whenYusaku Maezawa announced a giveaway on Twitter in January 2019, accumulating 4.4 million retweets. A similar tweet he made in December 2019 was retweeted 3.8 million times.[502]
The most tweeted moment in the history of Twitter occurred on August 2, 2013; during a Japanese television airing of theStudio Ghibli filmCastle in the Sky, fans simultaneously tweeted the wordbalse (バルス)—the incantation for a destruction spell used during its climax, after it was uttered in the film. There was a global peak of 143,199 tweets in one second, beating the previous record of 33,388.[503][504] The most discussed event in Twitter history occurred on October 24, 2015; the hashtag ("#ALDubEBTamangPanahon") forTamang Panahon, a live special episode of the Filipino variety showEat Bulaga! at thePhilippine Arena, centering on its popular on-air coupleAlDub, attracted 41 million tweets.[505][non-primary source needed][506] The most-discussed sporting event in Twitter history was the2014 FIFA World Cup semi-final between Brazil and Germany on July 8, 2014.[507]
According toGuinness World Records, the fastest pace to a million followers was set by actorRobert Downey Jr. in 23 hours and 22 minutes in April 2014.[508] This record was later broken byCaitlyn Jenner, who joined the site on June 1, 2015, and amassed a million followers in just 4 hours and 3 minutes.[509]
