Wait, but the 30-day windows were supposed to reverse this trend. Remember? That was the whole point. And it was definitely going to work. 

Warner Bros. DVD sales down 24 percent year over year. Sony sales down 20 percent. Paramount DVD sales down an excellent 44 percent year over year. 

The fundamental problem remains: most movies simply aren’t worth owning. The studios need to get on board with that fact, create a better system for renting all movies a massive number of times across a massive number of devices for a fair price, or they’ll get run over like their friends in the music industry.
