Xbox is the predecessor to Microsoft's Xbox 360 console.
The Xbox 360 is the successor to Microsoft's Xbox video game console, developed in cooperation with IBM, ATI, Samsung and SiS.
The Xbox 360 is the first console to have a near-simultaneous launch across the three major regions, and the first to provide wireless controller support at launch.
The promotional campaign for Xbox 360 began on March 14, 2005, with the opening of an alternate reality game called OurColony.
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.
Microsoft's retail strategy involves two different configurations of the Xbox 360: the Xbox 360 SKU, frequently referred to as the Xbox 360 Premium Package and an Xbox 360 Core System SKU.
John Carmack stated at QuakeCon 2005 that the Xbox 360 has "the best development environment I've seen on a console".
Microsoft XNA also includes other components such as the XNA Framework and XNA Build. Anyone can develop a game using XNA Game Studio Express, an IDE for homebrew developers, which was initially released in beta form on August 30, 2006.
Microsoft has stated that they intend to release more emulation profiles as they become available, with a goal of making the entire Xbox library playable on the Xbox 360.
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.
