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
Launched worldwide across 2005–2006, the Xbox 360 was initially in short supply in many regions, including North America and Europe. The earliest versions of the console suffered from a high failure rate, indicated by the so-called "Red Ring of Death", necessitating an extension of the device's warranty period. Microsoft released two redesigned models of the console: the "Xbox 360 S" in 2010, and the "Xbox 360 E" in 2013. As of June 2014, 84 million Xbox 360 consoles have been sold worldwide, making it the seventh-highest-selling video game console in history, and the highest-selling console made by an American company. Although not the best-selling console of its generation, the Xbox 360 was deemed by TechRadar to be the most influential through its emphasis on digital media distribution and multiplayer gaming on Xbox Live.
