The Xbox 360 is the second video game console produced by Microsoft, and was developed in cooperation with IBM, ATI, and SiS. The integrated Xbox Live service allows players to compete online and download content such as arcade games, game demos, trailers, TV shows, and movies. The Xbox 360 is the successor to the Xbox, and competes with Sony's PlayStation 3 and Nintendo's Wii as part of the seventh generation of video game consoles.

The Xbox 360 was officially unveiled on MTV on May 12, 2005, with detailed launch and game information divulged later that month at the Electronic Entertainment Expo (E3). The console sold out completely at release in all regions except in Japan, and, as of July 17, 2008, 20 million units have been sold worldwide according to Microsoft. The Xbox 360 comes in three different versions: the "Arcade" console, the "Premium" console, and the "Elite" console, each having its own selection of included and available accessories. Another version of the Xbox 360, called the "Core" which was available from launch, has since been discontinued for retail and replaced with the "Arcade".

Development

Known during development as Xenon, Xbox 2, Xbox FS, Xbox Next, or NextBox, the Xbox 360 was conceived in early 2003. In February 2003, planning for the Xenon software platform began, and was headed by Microsoft's Vice President J Allard. That month, Microsoft held an event for 400 developers in Bellevue, Washington, to recruit support for the system. Also that month, Peter Moore, former president of Sega of America, joined Microsoft. On August 12, 2003, ATI signed on to produce the graphic processing unit for the new console, a deal which was publicly announced two days later. The following month, IBM agreed to develop the triple-core CPU for the console. Before the launch of the Xbox 360, several alpha development kits were spotted using Apple's Power Mac G5 hardware. This was due to the system's PowerPC 970 processor running the same PowerPC architecture that the Xbox 360 would eventually run under IBM's Xenon processor.
