Xbox is buying Activision Blizzard.

Bobby Kotick exits on December 29 and Microsoft details other management changes

Activision Blizzard CEO Bobby Kotick formally announced that December 29 will be his last day at Microsoft Gaming after decades of running Activision and Activision Blizzard.

Microsoft bought Activision Blizzard for $68.7 billion on October 13, 20 months after announcing the deal that led to a tangle with regulators over antitrust concerns. Kotick and Brian Kelly bought a 25% stake in the near-bankrupt Activision (then Mediagenic) in 1990. In 1991, Kotick became CEO and they changed the name back to Activision and restructured it. Over the years, Kotick built it into the largest third-party publisher of games.
