We have this argument a lot at work
My personal feeling is that:
1. TV and Film content producers are too greedy, and don't want to collaborate on a system of streaming content to consumers that gives everyone access to what they want without licensing issues.
Netflix/Amazon prime etc go some ways to dealing with this, but fall short. Either with missing content, or content that gets pulled, or simply content that shows up long after it was available to people who pirate.
2. Models like Spotify and Steam work extremely well. They are not perfect, but I personally only use Spotify for music these days, and I buy all my games on Steam. The TV/Film industry is far behind the music and game industries in regards to the levels of content available to them for offline cache/streaming to customers.
3. My internet isn't great, I would struggle to stream at 1080p in real time, I doubt I could even stream at 720p. I have yet to see a TV/Film streaming service that lets you cache the files you download for watching later on.
4. The release delays between Cinema and Blu-Ray etc are needlessly long, why does it take 6 months to go from Cinema to Blu-Ray? By all means I think the Cinema should have content first, but the delay between Cinema and general release should be shorter.
5. In a perfect system content producers should be paid based upon views of their tv shows/films. The good stuff will 100% be watched more, and the people who make good shows/films should be rewarded for that appropriately.
I for one would be happy to pay £15 a month to get a service that could let me watch shows/films as they are shown (in the case of films parity with BR release not cinema), offline cache everything (or stuff I choose), and doesn't have ridiculous licensing issues.
I am sure that a lot of people would pay this too, the industry is missing out on a lot of cash, if they made it easier for people to get content legitimately people simply would not go and p2p download films and shows.
