One of the biggest events in esports kicked off from Shanghai on Wednesday night, pitting 18 teams against each other for a share of a $33 million prize pool.
The International is the annual championship for "Dota 2," a popular free-to-play computer game with millions of players around the world. "Dota 2" has more than 10 million active players each month, and each one of them can help contribute to the massive prize pool by spending money on the game.
Valve, the company behind "Dota 2," began hosting The International near their Seattle headquarters in 2011, and adopted a crowd-funding model to help support the game's active esports community.
The first International offered a $1.6 million prize pool, but it's ballooned in the years since. Last year's event gave away $25.5 million to the qualified teams, and this year's $33,039,566 prize pool could continue to increase as the tournament gets underway.
