Music/media question here- are you smart?

I have an essay question- All musicians rely on the media (eg. radio, TV, magazines) for their coninuing fame and success and the media in turn rely on these people for their profits.

I'm choosing to agree with this statement but I can't think of a person who I could refer to to support my view and some major points I could prove it with. Thankyou so much for your help- I really, really appreciate it!
