The Xbox 360 is a video game console produced by Microsoft, developed in cooperation with IBM, ATI, and SiS. Its Xbox Live service allows players to compete online and download arcade games and content such as game demos, trailers, TV shows, music videos, or rented 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 gaming systems.
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. It is the first console to provide near-simultaneous launch across the three major regions, and to provide wireless controller support at launch. The console sold out completely at release (with the exception of Japan) and as of Q2 2007, shipped 11.6 million units worldwide.[6][2] It is available in three versions as listed below.
