Xbox is the predecessor to Microsoft's Xbox 360 console.
The Xbox 360 sold out completely at release and by the end of September 2006 had sold 6 million worldwide.
Known during development as Xenon, Xbox 2, Xbox Next or NextBox, the Xbox 360 was conceived in early 2003.
The Xbox 360 takes a new approach to hardware compared to its predecessor. The CPU, named Xenon-CPU (or XCPU) at Microsoft and "Waternoose" at IBM, is a custom triple-core PowerPC-based design by IBM.
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.
