Another marketing advantage that HD-DVD has over Blu ray is that the average person won't have a clue what Blu ray is and what it does! Where as HD-DVD says it all in the title! The majority of people know what HD is and almost everybody knows what a DVD is! For they've already won it with their naming of the brand!
This was the same thing with VHS and Betamax! Betamax was actually the better technology but VHS won it on the name of its technology!
