But you are right that 50 different competing video services would be absurd. Perhaps it would be better to distribute videos in a marketplace, like steam did for games. They set their own prices so they don't have to worry about "exclusivity". And then they could allow for subscriptions to watch unlimited content for a set price, for people that value that.
The weird thing about movies is that they aren't like other commodities. People want to watch a specific movie, even if there are others that are just as good. Supply and demand doesn't work as well.
But I am worried about Netflix becoming monopolistic. They aren't now because they do have competition and have only a fraction of movies and TV shows available. But if it or something like it becomes the dominant video streaming service, they could charge consumers or producers whatever they want (within reason) because there are no other platforms to distribute your movies, and no one else has the ones you want to see.
