Mike Morhaime is resigning from his role as president of Blizzard Entertainment.

"After many years of working with some of the industry’s most talented people to create games and worlds for you to play in, I’ve decided it’s time for someone else to lead Blizzard Entertainment," Morhaime wrote .

The new president of Blizzard will be J. Allen Brack, who previously served as executive producer on World of Warcraft.

Activision Blizzard's CEO Bobby Kotick noted Morhaime's involvement in growing the studio into what it is today. "Thanks to Mike Morhaime's wonderful stewardship and masterful job of building a truly extraordinary team, epic games and a global community of beloved players, Blizzard is one of the very best game companies in the world."

Morhaime is one of three original co-founders of Blizzard, back when it was called Silicon & Synapse. He has been with the company for over 27 years, and will remain in an advisory manner going forward.
