> Why is this so hard for the film industry?
My theory is that the United States has compulsory licensing for music, but not movies: https://en.wikipedia.org/wiki/Compulsory_license#United_Stat...
To my knowledge, a radio station or music streaming service doesn't have to negotiate with the record label to play a given song, they just have to pay a small royalty as defined by law. However, that doesn't hold true for movies. Each video streaming service has to negotiate the right to carry a given movie with the film studio that owns it. Those film studios play the streaming services against one another, often allowing the exclusive right to offer certain content for a limited time, after which they then lease the rights to a competing service.
