Does anyone remember way back when HD DVD where going to be the new thing. Similar to betamax vs the VHS, HD DVD lost the battle. I'm not even sure you can still buy HD DVD's players. One of the reason Blu-ray won was because of their long list backers which included Sony, H-P, Disney however HD DVD had a solid bench which Paramount, Dreamworks and Universal Studios. The icing on the cake was the storage limitations of the HD DVD at only 30 GB where Blu-ray is almost double at 54GB. Despite using being very similar technology the Blu-ray won.
