The Xbox 360 sold out completely at release and by the end of September 2006 had sold 6 million worldwide.
The Xbox 360 was the first home console to be released in the seventh generation of game consoles and competes against Sony's PlayStation 3 and Nintendo's Wii.
Its Xbox Live service allows players to compete online as well as download games and additional content.
The Xbox 360 was released on November 22, 2005, in the United States and Canada; December 2, 2005, in Europe and December 10, 2005, in Japan.
Since Microsoft owns the intellectual property rights to the hardware used in the Xbox 360, they can easily switch to new fabrication processes or change suppliers in the future to reduce costs.
Xenos contains 48 unified shader units, which are capable of both vertex and pixel shading operations. This is in contrast to older graphics processor designs which utilize separate specialized units for these tasks.
Up to four controllers are supported by the Xbox 360, in the wireless form. However, there is a maximum of three wired controllers, as the Xbox 360 only has 3 USB slots.
