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.
