In 2006, the DVD was the most popular storage medium in the entertainment and computer industries. The development of high-definition (HD) technology created a need for a format with greater storage capacity. Instead of agreeing on a single standard for a new HD disc, however, key players had formed two rival camps. The Blu-ray and HD-DVD formats each had distinct technical advantages and enjoyed the support of different groups in the consumer electronics, personal computer, and entertainment industries. Set at a time when companies were starting to release products for each format, this case includes a brief history of the format war along with information on the rival camps and their product offerings. Also, covers factors that might affect the future course of this battle, such as the role of copy protection features in HD devices, the bundling of each format with video game consoles, and competing modes of delivering video content. A revised version of an earlier case.
