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
The console was publicly unveiled under the name Xbox One on May 21, 2013 in a press conference designed to cover the unit's broad multimedia and social capabilities. A second press event for the console was held during E3 2013, focusing on its video game-oriented functionality. At that time, Microsoft announced that the console would be released in 21 different markets on November 22, 2013, but this was later amended down to 13. The change, which pushed the release date for the other eight markets to 2014, was attributed to unforeseen complexity in localizing the device's voice recognition capabilities. Later, in September 2014, the Xbox One was released in 26 markets, including remaining markets in Europe, the Japanese market, and Middle Eastern markets.
