query: When was the Xbox first introduced?
passage: Xbox
Xbox is a video gaming brand created and owned by Microsoft of the United States. It represents a series of video game consoles developed by Microsoft, with three consoles released in the sixth, seventh, and eighth generations, respectively. The brand also represents applications (games), streaming services, and an online service by the name of Xbox Live. The brand was first introduced in the United States in November 2001, with the launch of the original Xbox console.
passage: Xbox (console)
The Xbox was the first video game console to feature a built-in hard disk drive, used primarily for storing game saves and content downloaded from Xbox Live. This eliminated the need for separate memory cards (although some older consoles, such as the Amiga CD32, used internal flash memory, and others, like the TurboGrafx-CD, Sega CD, and Sega Saturn, had featured built-in battery backup memory prior to 2001). An Xbox user could rip music from standard audio CDs to the hard drive, and these songs were used for the custom soundtracks in some games.
