Blizzard has been known to have a very lean division. While it is not really as lean as Valve´s division, Blizzard has now decided to open up a new section within the company.
This new section has been created solely with the purpose of handling the Overwatch World Cup and the Overwatch League. The overwatch League is an ambitious league that Blizzard is trying to sell to some of the top companies in the world. With teams valued at almost $20 million there has been some resistance from the teams to pursue teams with such high price tags.
Blizzard Entertainment, Inc. has formed a dedicated division within the company that will handle management, operation, sales, and distribution for Overwatch®esports programs, including the Overwatch League™ and Overwatch World Cup. In addition to bringing together some of the most talented people from across the entire organization, this effort includes the full integration of Major League Gaming, acquired in 2015, into Blizzard and also leverages some of the best and brightest from traditional sports, esports, and entertainment.
