HD DVD
????Launched in 2006, Toshiba's high-definition density DVD was intended as the successor to the standard DVD disc format. While a standard DVD commonly packs 4.7 GB of information on each side, an HD DVD could store more than triple that. But Blu ray's more effective marketing campaign, and the inclusion of a Blu ray drive on the Playstation 3 console, helped turn the tide in the competition's favor. By 2007, Blu ray discs were outselling HD DVDs, and in 2008, Toshiba killed the format.
