15 January 2026 — Wikipedia, the world’s largest online information resource, turns 25 today, marking a quarter century of making trustworthy, human-powered knowledge accessible worldwide. Through a Wikipedia 25 campaign launched today,the Wikimedia Foundation — the nonprofit that operates Wikipedia — invites everyone to discover Wikipedia’s journey over the last 25 years, celebrate the volunteers who make the site possible, and be part of the platform’s future.

“Wikipedia is a digital wonder of the world, unlike anything else. It has overcome countless challenges and changes in its time, thanks to the people behind it and their unwavering commitment to sharing free, reliable knowledge with the world,” saidMaryana Iskander, Chief Executive Officer of the Wikimedia Foundation.“With billions of monthly visits and an ever-growing number of organizations relying on Wikipedia’s free, verified knowledge, this platform has become integral to the architecture of the entire internet.”

New Wikipedia birthday campaign: docuseries, time capsule, and more

Today, the Wikimedia Foundation released for the first time avideo “docuseries,” sharing a behind-the-scenes look at the lives and stories of Wikipedia volunteer editors around the world. All of the knowledge on Wikipedia is created and maintained by a global community of nearly 250,000 volunteer editors who write, edit, and fact check information according torigorous standards on neutrality and reliability.

The series stars eight of these volunteers and spotlights their unique purpose and passions for contributing to the online encyclopedia. They include a Californian who has spent two decades documenting hurricanes and storms, an Indian medical doctor who shared critical COVID-19 information during the global pandemic, an elderly librarian in Tokyo making knowledge available in Japanese, and more. Their stories underscore that, even andespecially in the age of AI, knowledge is human, and knowledge needs humans.

The Foundation also launched today a“25 Years of Wikipedia” time capsule, allowing Wikipedia fans worldwide to delve into the past, present, and future of this treasured global resource. Users can listen to Founder Jimmy Wales share in his own words memories from Wikipedia’s origin story, including when he himself installed the site’s very first servers. The capsule also explores Wikipedia’s role during major global events, such as when Wikipedia’s servers almost collapsed in 2009 from site visits following Michael Jackson’s death. It showcases some of the most weird and wonderful parts of Wikipedia, like an article on aprescient octopus named Paul.

In looking to Wikipedia’s future, anew interactive quiz — also released today — invites people worldwide to discover which Wikipedia future best represents them. The futures were imagined by a group of Wikipedia editors, young children, professional futurists, and artists, representing a range of visions for the Wikipedia of tomorrow.

Wikipedia in the age of AI

Wikipedia has become the backbone of knowledge on the internet. For 25 years, Wikipedia and its global volunteer community have navigated technology disruptions, regulatory changes, and growing mistrust across the information landscape, among other shifts. Through it all, they have — and will continue to — adapt and evolve to ensure everyone, everywhere can continue to access and share knowledge.

In the AI era, Wikipedia and its human-created and curated knowledgehas never been more valuable. Today, Wikipedia is among the top-ten most-visited global websites, and it is the only one to be run by a nonprofit. Its 65 million articles in over 300 languages are viewed nearly 15 billion times every month, and its knowledge power generative AI chatbots, search engines, voice assistants and more. Wikipedia is one of thehighest-quality datasets used in training Large Language Models.

Wikipedia’s progress over the last 25 years highlights its increasing relevance to the online world today. These are a few of the ways it has grown and evolved over the years:

New partnerships with tech companies support Wikipedia’s sustainability:Tech companies that rely on Wikipedia content must use it responsibly and help sustain Wikipedia for the future. One key way to do this is through theWikimedia Enterprise platform. Developed by the Wikimedia Foundation, Wikimedia Enterprise is a commercial product for large-scale reusers and distributors of content from Wikimedia projects. Over the past year, several companies — includingEcosia, Microsoft, Mistral AI, Perplexity, Pleias, and ProRata— became new Wikimedia Enterprise partners, joining existing partners such asAmazon,Google, and Meta. They can access content from Wikimedia projects at a volume and speed designed specifically for their needs, while directly supporting our nonprofit mission.
Implementing an AI strategy that puts humans first:The Foundation’s recentAI strategy directs future investments and developments in AI to support the human contributors at the core of Wikipedia, so that they can spend their valuable time on what they want to accomplish and not on how to technically achieve it.
Strengthening our tech infrastructure:Continuous improvements have been made to Wikipedia’s tech infrastructure since 2001 to make it one of the most accessible and multilingual sites in the world.Updates to Wikipedia’s desktop interface anddark mode have greatly improved user accessibility; we’ve opened newdata centers to quicken load times; and Wikipedia apps foriOS andAndroid allow Wikipedia fans to access content right from their mobile devices.
Closing knowledge gaps:Knowledge on Wikipedia today has grown to be more representative and reflective of the world through dedicated efforts inlanguage translation andcommunity-led initiatives to increase the spectrum of volunteer editors and content on the site. Further,Abstract Wikipedia aims to make the reliable information on Wikipedia available in all languages; the project was one of five finalists of MacArthur Foundation’s 100&Change grant competition last year.
Engaging the next generation of readers and contributors:Throughnew experiments such as online games and short content for social media, we are discovering innovative ways that Wikipedia can reach new users, respond toglobal trends, and meet the evolving needs of users in a changing internet landscape.
