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.
Xbox 360 technical problems
In December 2005 (shortly after the Xbox 360's release in the United States and Canada on November 22, 2005 and around its release in Europe and Asia in early December 2005), reports of unidentifiable noises from the Xbox 360 were appearing on Internet message boards. In response to the problem, Microsoft offered in December 2005 to replace only the "Perfect Dark Zero" video game "even if it was not the game that was scratched." The scratched disc problem reportedly affected only a small percentage of Xbox 360 units, however it became apparent in December 2005, through message board reports and growing media coverage.
