It appears as if Twitch and Blizzard are banking on the idea that the Overwatch League is going to be around for more than just a minute. Both companies announced this morning that they have signed a multi-year media partnership, "ensuring that every match of the world's first major global city-based esports league will be readily available to fans across the globe."
Below are a couple quotes from the release sent out this morning, but the short version is that the games will be exclusively broadcast on Twitch for the regular season, playoffs, and championships. No word was given as to how long the deal is set for, but "multi" implies that we're looking at somewhere between three to five at least.
"Our fans love to engage with content on Twitch, and we wanted to drive significant viewership of the Overwatch League in its inaugural season and beyond," said Armin Zerza, COO of Blizzard Entertainment. "That's why this historic and ground-breaking partnership is perfectly suited for Activision Blizzard, for Twitch, and—most importantly—for our growing global fanbase."
"The Overwatch League is making a major impact on esports by reshaping the industry with city-based teams," said Kevin Lin, COO of Twitch. "Given Overwatch's consistent reign as a top viewed game by our community, we look forward to offering their pioneering style of league play to a large and passionate fanbase that will be able to bond over not only their favorite plays, but hometown pride."
