Microsoft CEO Steve Ballmer has announced that he will retire within the next year, contingent upon selection of his successor. In the meantime, Ballmer will continue leading Microsoft’s effort to become a device and services company. Ballmer has been with Microsoft since 1980, when Bill Gates hired him as the company’s first business manager. Ballmer took the reins in 2000 when Gates retired and has overseen numerous major products (of varying success), including multiple versions of Windows and Office, Xbox, Zune, Windows Phone, and Surface. Despite many criticisms of his leadership, he doubled Microsoft’s profits during his tenure as CEO.
