DiGiovanni’s Major League Gaming is one of the most prominent competitive-gaming organizations in the country. It holds major events every few months in live venues. In the video, DiGiovanni talked about how MLG’s impressive viewer engagement — viewers often watch 3.5 hours uninterrupted — has brands very interested in advertising.

Twitch is one of the biggest game-streaming video sites. Lin talked about its massive growth which led to 29 million unique viewers in February.

Blizzard is one of the primary competitive-gaming developers. Its Starcraft II is arguably the most important game in all of e-sports. Morhaime spoke to an Blizzard’s interest in consolidation in e-sports.
