You can watch the $10+ million Dota 2 tournament The International on Twitch, or in-game, or, huh, even on ESPN. Valve is collaborating with the sports network for coverage this weekend.
Notably, ESPN2 will have an exclusive preview of Monday's final match featuring game highlights, analysis, and interviews with players and Valve's Gabe Newell. That airs Sunday at 8:30pm Pacific.
ESPN3 viewers will also be able to watch The International matches and coverage -- the stuff that can be found on Twitch, etc. -- this Friday through Monday as the Championships unfold. You're coming along just fine, eSports.
