I honestly do not believe that the movie studios are motivated to improve the current system. Perhaps they feel that the current, fractured delivery system serves their interest more than something central and comprehensive. It certainly encourages the customer to subscribe to a service like Netflix, perhaps also to rent a new release on iTunes and eventually possibly buying that same release when its price drops. That's getting paid three times for the same content!
Movie studios have the least exposure to piracy risk other than online multiplayer games and console games.
You can't get a good copy of a movie until DVDs and brs are released. Cams and TSs are terrible.
If something like popcorn time went mainstream they would just stop releasing disc media and downloads until well after the theatre stopped playing.
TV is the industry that should be worried. If popcorn time goes mainstream we'll never see high budget cable content ever again. Just 100% low budget sitcoms, soap operas and reality TV. But not with constant in show advertising that scenesters can't edit out.
Bingo. The goal of the movie industry is simply to make more money, and to prevent any challenge to their stranglehold on content... if that is achieved by balkanized delivery systems, that's what they will push for.
