Microsoft has grown significantly since its founding in 1975. It began by partnering with IBM and launched its first Windows operating system in 1982. Major releases included Windows 95, 98, 2000, XP, Vista, 7, and 8. In 2012, Microsoft's top partners were Avanade, HP, and Catapult Systems. Microsoft seeks to grow its market share in smartphones and cloud computing while expanding services around popular franchises like Halo and partnerships like Nokia. It remains the dominant player in desktop operating systems but faces strong competition from Android and iOS in mobile.
