Company man Satya Nadella, who has served Microsoft since 1992, has been anointed CEO. He’s seen as a “safe” choice who will focus on company continuity. Nadella is only the company’s third CEO and has pegged Microsoft’s future to services and the cloud. In a bit of boardroom musical chairs, the previous CEO, Steve Ballmer, will take the chairman’s helm, vacated by founder Bill Gates, who will serve as a technology advisor. Gates’ return might be even bigger news for eager investors, one analyst says, than any word from the top office.
