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. As of April 19, 2012, 67.2 million Xbox 360 consoles have been sold worldwide.
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.
Several major features of the Xbox 360 are its integrated Xbox Live service that allows players to compete online, download arcade games, game demos, trailers, TV shows, music and movies and its Windows Media Center multimedia capabilities. The Xbox Live also offers region specific access to third-party media streaming application such as Netflix and ESPN in the US or Sky Go in the UK.
At their E3 presentation on June 14, 2010, Microsoft announced a redesigned Xbox 360 that would ship on the same day. The redesigned console is slimmer than the previous Xbox 360 model and features integrated 802.11 b/g/n Wi-Fi, TOSLINK S/PDIF optical audio output, five USB 2.0 ports (compared to the three from older versions) and a special AUX port. Older models of the Xbox 360 have since been discontinued. The first new console to be released features a 250 GB hard drive, while a later, less expensive SKU features 4 GB internal storage.
