It's also not the same thing as from video cassette to dvd. As you didn't have to have a better tv with it too.
you also have to get a different TV for it to be useful. Yes thats what's being sold now. But many people that do not have lots of money still use the old fat tv's that would get no benefit from blu-ray. Also factor in the added costs of a blu-ray versus dvd.
DD still has obstacles as well in the future such as with bandwidth and things related to the net neutrality act in the future
