The International 2013 was hosted again at the Benaroya Hall in Seattle from August 7–11. Sixteen teams participated, thirteen of which received direct invitations, and the final three being decided in two qualifying tournaments and a match at the start of the tournament.[15] In May 2013, it was announced that an in-gamebattle pass, known as the Compendium, would be available for purchase that allowed for the tournament's prize pool to becrowdfunded. A quarter of the total revenue from the Compendium was added to the base $1.6 million prize pool.[16] The prize pool eventually reached over $2.8 million, making it the largest prize pool in esports history at the time.[17]KCPQ news anchor Kaci Aitchison acted as a host at the event, providing behind-the-scenes commentary and player interviews.[18] The International 2013 was viewed by over a million concurrent viewers at its peak, via live streaming websites such asTwitch.[19]

In April 2015, Valve announced the introduction of the Dota Major Championships, a series of four annual tournaments, one for each season. The Fall, Winter and Spring Majors were sponsored by Valve but organized by third-party hosts at various international locations, while the Summer event was the International.[26][27] This format was first implemented for the 2015–2016 season, featuring theFrankfurt Major, theShanghai Major and theManila Major, culminating inThe International 2016.[28] In the subsequent 2016–2017 season, the number of Major tournaments was reduced to three: theBoston Major, theKiev Major andThe International 2017.[29] Starting with The International 2017, the total number of participating teams was increased from 16 to 18.[30]
For the 2017–2018 season, Valve introduced the Dota Pro Circuit, a series of tournaments awarding qualifying points. The eight teams with the highest point totals at the end of the season received direct invitations toThe International 2018, while another ten teams qualified via regional qualifier tournaments.[29][31][32][33] The circuit was implemented to provide more "clarity and transparency" in the selection process for direct invites.[34][35] Over the course of the 2017–2018 season, the Dota Pro Circuit comprised nine Majors (excluding The International 2018) and 13 Minors.[36]
The International 2020 was the first International to skip a year, as it was postponed due to theCOVID-19 pandemic.[37] Ahead of the event, originally scheduled to be held inStockholm, Sweden, the Swedish Sports Federation voted to deny recognition of esports as a sporting event, making it difficult for Valve to help international players to secure travel visas for participating there.[38] Valve later rescheduled the event and rebranded it asThe International 2021, which was held at theArena Națională inBucharest, Romania, in October 2021.[39] It set a record for the largest prize pool of any single esports event at $40 million.[40]

With the exception of the inaugural edition, in which all teams were invited, subsequent tournaments have featured a mixed qualification process.[1] A portion of the participating teams receive direct invitations, typically based on their performance throughout the year, while the remaining slots are filled through qualifier tournaments.[62] The main tournament typically begins with a group stage conducted in around-robin format, followed by a main event structured as adouble-elimination bracket.
Since The International 2013, the tournament's prize pool is primarilycrowdfunded through abattle pass called the Compendium, which raises money from players buying them to get exclusive in-game virtual goods and other bonuses.[63][64] 25% of all the revenue made from yearly Compendiums go directly to the prize pool.[65][66] The contribution of players from thegame community is the main source of prize pool for the International.[67] Until 2022, each iteration of The International has surpassed the previous one's prize pool.The International 2021 had the largest prize pool, awarding $40 million (£29 million) in total to participating teams.[68][69] Prize pools began to decline by the mid-2020s;The International 2024 had the smallest since the introduction of crowdfunding at $2,602,164.[70]
The Aegis of Champions is a trophy that is awarded to the champions of an International. The reverse side of it is permanently engraved with the names of each player on the winning team.[71][68] The Aegis is a shield inspired by Norse and Chinese designs, with it molded in bronze and silver by the prop studio,Weta Workshop.[71] Miniature replicas of it are also sometimes awarded to compendium owners for having a high enough level in it.[72]
As with traditional sporting events, The International feature pre- and post-game discussion by a panel of analysts (left), with in-match casting being done byplay-by-play andcolor commentators (right).
The primarymedium for International coverage is through thevideo game live streaming platformTwitch, which is done by a selection of dedicated esports organizations and personnel who provide on-sitecommentary, analysis, match predictions, and player interviews surrounding the event in progress, similar to traditional sporting events.[19][73] Multiple streams are provided in a variety of languages, mainly in English, Russian, and Chinese. The International also sometimes provides a "newcomer stream" that is dedicated to presenting games for viewers unfamiliar with the game.[74]
In 2014,Valve released a freedocumentary,Free to Play, which followed three players during their time at the first International in 2011.[75][76] In 2016, Valve began producing an episodic-based documentary series titledTrue Sight, considered aspiritual successor toFree to Play.[77] Several more episodes of it have been filmed, showcasing the 2017, 2018, 2019, and 2021 tournaments.[78][79][80][81] However,True Sight was discontinued after the 2022 tournament.
