Valve's The International 2013 Dota 2 Championships doubled last year's record viewership and peaked at a simultaneous online viewership of over 1 million gamers, Valve announced today.

The 1 million peak simultaneous figure is made up of those who watched through Twitch, Gamefy in China, and Valve's own services. It does not include viewers who watched through international broadcasts or other means.

The International 3 came roughly 100,000 viewers short of tying the all-time eSports record set by Riot's League Championship Series Season 2 finals with 1.1 million.

Competitive gaming team Alliance from Sweden picked up $1.43 million after finishing first place in this year's tournament.

The International 3 event kicked off on August 3, with 16 of the best Dota 2 teams flown in from around the world to compete. The event was hosted at Benaroya Hall in Seattle, Washington.

The prize pool for The International 3 totaled $2.87 million, establishing its record as the largest prize pool for a single competitive gaming event. Nearly 400,000 people tuned in live for the first day of the event, and 600,000 on the second and third days, surpassing last year's peak numbers.
