The International (Dota 2)

The first International was held at Gamescom in 2011

Valve announced the first edition of The International on August 1, 2011. 16 teams were invited to compete in the tournament, which would also serve as the first public viewing of Dota 2.[16] The tournament was funded by Valve, including the US$1 million USD grand prize, with Nvidia supplying the hardware.[17][18] It took place at Gamescom in Cologne from August 17–21 the same year.[2] The tournament started with a group stage in which the winners of each of the four groups were entered into a winner's bracket, and the other teams entered the loser's bracket. The rest of the tournament was then played as a double-elimination tournament.[19] The final of this first tournament was between Ukrainian-based Natus Vincere and Chinese-based EHOME, with Natus Vincere winning the series 3-1.[20] EHOME won US$250,000, with the rest of the 14 teams splitting the remaining $350,000.[21]

The International as an recurring annual event was confirmed in May 2012.[22][23] The International 2012 was held at the 2,500 seat Benaroya Hall in Seattle from August 31 to September 2, with teams situated in glass booths on the main stage.[24] The total prize pool remained $1.6 million, with $1 million for the winning team.[25][26] The previous winners, Natus Vincere, were beaten 3-1 by Chinese team Invictus Gaming in the grand finals.[27] In November 2012, Valve released a free documentary on the event that featured interviews with the teams, and following them from the preliminary stages through to the finale.[28]

The International 2014

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.[29] In May 2013, it was announced that an in-game battle pass, known as the Compendium, would be available for purchase that allowed for the tournament's prize pool to be crowdfunded. A quarter of all revenue from it was added to the base $1.6 million prize pool.[30] The prize pool eventually reached over $2.8 million, making it the largest prize pool in esports history at the time.[31] KCPQ news anchor Kaci Aitchison acted as a host at the event, providing behind-the-scenes commentary and player interviews.[32] The International 2013 was viewed by over a million concurrent viewers at its peak, via live streaming websites such as Twitch.[33]

The International 2014 took place from July 18–21 at the KeyArena in Seattle.[34] For the event, eleven teams would receive direct invites, with an additional four spots determined by regional qualifiers taking place between May 12–25. The sixteenth spot would be determined by a wild card qualifier between the runners-up from the regional competitions.[35] The tickets for the event were sold out within an hour of going on sale that April.[36] The tournament's crowdfunded prize pool again broke esport records for being the largest in history, with it totaling over $10.9 million.[37] As a result, eight Dota 2 players became the highest earning players in esports, surpassing the top earning player at the time, Lee "Jaedong" Jae-dong of StarCraft.[38] The event was also broadcast on ESPN networks for the first time.[39]

The tournament was expanded to 18 teams for The International 2017 onwards, an increase from the previous 16.[40] The International 2020 was the first International to skip a year, as it was delayed indefinitely due to the COVID-19 pandemic.[41] Valve announced that the 2020 edition of the Dota 2 tournament, known as The International, that was set to take place at the Ericsson Globe arena in Stockholm this August will no longer happen this summer and may be pushed back until 2021. In fact, Valve says it simply doesn’t know when it can announce concrete dates going forward.[42]

The International features a series of tournaments before the event, known as the Dota Pro Circuit (DPC), with the top 12 ranking teams receiving direct invitations based on their final standings.[43][44][45] Besides the directly invited DPC teams, an additional team from the Commonwealth of Independent States (CIS), China, Europe, North America, South America, and Southeast Asia regions each earn an invite by winning regional playoffs, bringing the total number of participating teams up to 18.[46][47] At the International, two separate best-of-two round robin groups consisting of nine teams each are played, with lowest placed team from both at the end of the stage being eliminated.[48][49][40] The remaining 16 teams then move on to the double elimination main event at the hosted venue, with the top four finishing teams from both groups advancing to the upper bracket, and the bottom four advancing to the lower bracket.[49][48] The first round of the lower bracket is treated as single-elimination, with the loser of each match being immediately eliminated from the tournament.[48][40] Every other round of both brackets is played in a best-of-three series, with the exception being the Grand Finals, which is played between the winners of the upper and lower brackets in a best-of-five series.[48]

Starting with The International 2013 onward, the tournament's prize pool began to be crowdfunded through a type of in-game battle pass called the "Compendium", which raises money from players buying them to get exclusive in-game virtual goods and other bonuses.[50][51] 25% of all the revenue made from yearly Compendiums go directly to the prize pool.[52][53] Each iteration of The International has surpassed the previous one's prize pool, with the most recent one, The International 2019, having one at over $34 million.[54][55][56][57]

In 2014, Valve released a free documentary, Free to Play, which followed three players during their time at the first International in 2011.[63][64] In 2016, Valve began producing an episodic-based documentary series titled True Sight, considered a spiritual successor to Free to Play.[65] Several episodes of it have been filmed at International since, showcasing the 2017, 2018 and 2019 tournaments.[66][67][68]
