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
On November 22, 2013, Microsoft confirmed that it had sold one million Xbox One consoles within its first 24 hours of being available. Based on approximately 102,000 shopping receipts tracked by InfoScout, 1,500 of which included a purchase of either a video game or a video game console, the Xbox One was the highest-selling console during the Black Friday sales period in the United States.
