2013 not only broke records for viewers but also for the cold hard cash pro gamers could walk away with. The DOTA 2 International created a prize pool of over $2.8 million while season 3 of League of Legends World Championship winners could walk away with over 2 million clams. In a year that saw the very first competitive tournament for Call of Duty: Ghosts, the Call of Duty: Black Ops 2 Championship handed out over a million bucks.

So yes, the prize pools are getting bigger. But the big news is that most of the cash raised for competitions like The International were raised through voluntary in-game purchases from players of DOTA 2. eSports support isn't just coming from corporations but has taken to its grass-roots fan base.
