Companies spend millions (billions) investing in traditional sports and athletes, and most of them still shun eSports. This could be a very big and costly mistake in the light of the growth this sport (let's call it a sport once and for all. It's aired on ESPN, so it's a sport) has seen in the past 5 years. From small hotel lobbies and anonymous Internet cafes, it's grown to be one of the most watched events of the year. The Worlds 2016 (League of Legends Annual World Tournament) has been taking place over 15 days, and has had over 370 MILLION Total hours of live eSports watched, for 396 Million Cumulative Daily Unique Impressions.
Now if that's not enough, consider the prize pool for DOTA 2 (League of Legends's Competitor): More than US $19 Million in Contributed Prize Pool for the event. That is more than the prize pool for the Super Bowl or the World Series of Baseball. So the money is there, the interest of viewers too. It's not a niche in sports as most people still think it is, it is eSports. Period.
