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 360
At launch, the Xbox 360 was available in two configurations: the "Xbox 360" package (unofficially known as the 20 GB Pro or Premium), priced at US$399 or GB£279.99, and the "Xbox 360 Core", priced at US$299 and GB£209.99. The original shipment of the Xbox 360 version included a cut-down version of the Media Remote as a promotion. The Elite package was launched later at US$479. The "Xbox 360 Core" was replaced by the "Xbox 360 Arcade" in October 2007 and a 60 GB version of the Xbox 360 Pro was released on August 1, 2008. The Pro package was discontinued and marked down to US$249 on August 28, 2009 to be sold until stock ran out, while the Elite was also marked down in price to US$299.
