The Xbox 360 is the second video game console produced by Microsoft, and the successor to the Xbox. The Xbox 360 competes with Sony's PlayStation 3 and Nintendo's Wii as part of the seventh generation of video game consoles.
A prominent feature of the Xbox 360 is its integrated Xbox Live service that allows players to compete online and download content such as arcade games, game demos, trailers, TV shows, and movies. Major features of the console include its Windows Media Center multimedia capabilities, mandatory support of high definition in all games, movie rentals and game downloads from its online marketplace and the ability to watch movies on the (now discontinued) HD DVD format via an add-on drive.
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 upon release in all regions except in Japan, and, as of August 2009, over 31 million units have been sold worldwide.The Xbox 360 is currently available in two configurations—the "Arcade" and the "Elite"—and each has its own selection of accessories.
