Satya Nadella, the quiet and self-effacing Microsoft enterprise chief, prevailed over much splashier outside candidates and was named CEO of the software giant on Tuesday. He is only the third CEO since the company’s founding, replacing Steve Ballmer. The first Microsoft CEO, of course, was co-founder and chairman Bill Gates. As part of the changes at the top and perhaps even more significantly — at least from a symbolic perspective — Gates will be shedding his chairman role at the company, to be replaced by director John Thompson, former CEO of Symantec. Instead, Gates will be spending more time helping Nadella, as Re/code had reported several weeks ago, especially in the technology and product area, with the title of “technology advisor,” working full-time several days a week at Microsoft.
