Blizzard's highly touted and much-promoted Overwatch League, a professional eSports league dedicated to the game, had a very successful first week, it seems. Blizzard announced today that the league's first week of programming netted more than 10 million viewers.

The inaugural Overwatch League season started last week in Los Angeles with four days of matches between the 12 teams. The 10 million figure for people who watched the first wave of competition spans all networks, including Twitch, along with Activision's own MLG service. It also covers international partners such as ZhanQi TV, NetEase CC, and Panda TV in China.
