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.
Xbox One system software
The Xbox One was not backward compatible with either the original Xbox or the Xbox 360 console at launch, and Microsoft had admitted that attempts to use cloud streaming to allow Xbox 360 games to be played on Xbox One proved to be "problematic". However, during its E3 press conference on June 15, 2015, Microsoft announced plans to introduce Xbox 360 backward compatibility using the software method on the Xbox One. Supported Xbox 360 games are supposed to run within a software emulator provided by the updated system software, implementing both the hardware and software of the Xbox 360. Xbox One recording and broadcasting features are supported along with Xbox 360 multiplayer, achievements and cloud save access.
