It's official: Toshiba has discontinued HD DVD, reports Variety Asia. That's the end of the format -- Toshiba is the owner of the format -- and of the high-def DVD format war. The move follows a string of recent setbacks for HD DVD, and should give a boost to that format. It may also delay adoption of Internet downloads as a format, at least until there's a better way to get Internet content onto TV sets. Blu-ray wins - unless the Internet does.
