Microsoft has promoted executive Don Mattrick to "president" of its Interactive Entertainment Business, which includes the company's Xbox business, as well as its PC and mobile gaming efforts. Previously, Mattrick was labeled a "senior vice president," though his responsibilities have not appeared to change in quite some time. He has led the Interactive Entertainment segment since July 2007.
In May, Microsoft announced the pending retirement of Xbox head Robbie Bach from his position as president of the Entertainment & Devices Division (under which Mattrick's Interactive Entertainment Business is filed). Since that time, the company has seemingly done away with Bach's position (just what was he doing, anyway?), since Mattrick and colleague Andy Lees, now president of the Mobile Communications Business, where already overseeing the E&D Division's two main businesses. Both executives report directly to CEO Steve Ballmer.
