Entertainment
The Entertainment and Devices Division produces the Windows CE OS for embedded systems and Windows Phone for smartphones. Microsoft initially entered the mobile market through Windows CE for handheld devices, eventually developing into the Windows Mobile OS and now, Windows Phone. Windows CE is designed for devices where the OS may not directly be visible to the end user, in particular, appliances and cars. The division also produces computer games that run on Windows PCs and other systems including such as Age of Empires, Halo and the Microsoft Flight Simulator series, and houses the Macintosh Business Unit which produces Mac OS software including Microsoft Office 2011 for Mac. Microsoft's Entertainment and Devices Division designs, markets, and manufactures consumer electronics including the Xbox 360 game console, the handheld Zune media player, and the Internet appliance MSN TV. Microsoft also markets personal computer hardware including mice, keyboards, and various game controllers such as joysticks and gamepads.
