umm last year was the biggest box office year ever.. DVD has only been around for 10 years? People bought video tapes before, but not like they did DVD's. How could the movie industry, while raking in box office cash, now rely on dvd sales?
its pretty obvious that with dvd's being out so long, alot of people have built up their collections, and just buy new ones as they come out. CD's suffered the same problem, when people upgraded from vinyl and cassette. (yes i know it can be disputed that cd is an upgrade from vinyl).
this is why record companies try to introduce new meda every so often, so they can resell their old catalogs.
The DVD market is oversaturated.. the format so popular, that almost anything can be found on it, and movie companies dropping prices to ridicously low prices to compete with other products.
I imagine they'd want to promote bluray so they can get people to buy old movies again. But the fact they are now depend on DVD sales to turn a profit, when box office revenues are record breaking.. is a wtf? shouldn't DVD have been gravy.. at what point in the last 10 years did movie companies become reliant on it?
