Xbox
The original Xbox was released on November 15, 2001, in North America, February 22, 2002, in Japan, and March 14, 2002, in Australia and Europe. It was Microsoft's first foray into the gaming console market. As part of the sixth-generation of gaming, the Xbox competed with Sony's PlayStation 2, Sega's Dreamcast (which stopped American sales before the Xbox went on sale), and Nintendo's GameCube. The Xbox was the first console offered by an American company after the Atari Jaguar stopped sales in 1996. The name Xbox was derived from a contraction of "DirectX Box", a reference to Microsoft's graphics API, DirectX.
List of Xbox games compatible with Xbox 360
At its launch in November 2005, the Xbox 360 did not have hardware-based backward compatibility with Xbox games due to the different types of hardware and architecture used in the Xbox and Xbox 360. Instead backward compatibility was achieved using software emulation. When the Xbox 360 launched in North America 212 Xbox games were supported while in Europe 156 games were supported. The Japanese market had the fewest titles supported at launch with only 12 games. Microsoft's final update to the list of backward compatible titles was in November 2007 bringing the final total to 461 Xbox games.
