I think another thing is that we don't really want exclusivity. We accept that it is in the artist's interest to be on sale in every place where they sell music.
In a way it costs thousands dollars before you could actually go out to put the show on because you'll need equipments, all the lights you know, and that's more just going out and playing you know.
I think TV is much more the writer's medium and film is about the director and their vision and how you can collaborate with them and see that through to the end. They are so different.
