Xbox was first released on November 15, 2001 in North America, February 22, 2002 in Japan, and on March 14, 2002 in Europe.
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.
Due to its early launch, the Xbox 360 has a one-year lead on both of its competitors, Sony's PlayStation 3 and Nintendo's Wii.
The console's graphical user interface is the Xbox 360 Dashboard; a tabbed interface that features four "Blades".
Updated emulation profiles can be obtained through Xbox Live, by burning a CD with profiles downloaded from Xbox.com, or by ordering an update disc from Microsoft.
