Xbox Live
When the Xbox launched on November 15, 2001, the as-yet unnamed online service was destined for a Summer 2002 deployment. Xbox Live was finally given a name at E3 2002 when the service was unveiled in its entirety. Sound-dampened booths and broadband-connected Xbox consoles—featuring an early version of "Unreal Championship"—demonstrated the service on the show floor. The Epic title was one of the flagship titles for the service, which was slated for a debut on November 15, 2002, marking the anniversary of the Xbox launch. Microsoft announced that 50 Xbox Live titles would be available by the end of 2003. Utilizing the required broadband bandwidth, Xbox Live featured a unified gaming "Friends List", as well as a single identity across all titles (regardless of the publisher), and standardized voice chat with a headset and communication, a feature that was still in its infancy.
List of Xbox games compatible with Xbox 360
At its launch in November 2005, the Xbox 360 did not have hardware-based backward compatibility with Xbox games due to the different types of hardware and architecture used in the Xbox and Xbox 360. Instead backward compatibility was achieved using software emulation. When the Xbox 360 launched in North America 212 Xbox games were supported while in Europe 156 games were supported. The Japanese market had the fewest titles supported at launch with only 12 games. Microsoft's final update to the list of backward compatible titles was in November 2007 bringing the final total to 461 Xbox games.
