Junction, there's no basis for that. But there is history for the other way - there were a lot of local TV-channels that made ample profits and were in business for two decades. So profitable that the big networks went thru and bought them up.
Personally, I'm much rather risk it. Why give Entitlements to groups that don't earn it? And puh-leeze, the threats of "They'll raise the prices!" - heck, they raise prices because the sun rises. A cloud appears. I'd love to see TV channels survive on the programming their viewers really like, rather than having the Judge Judy's, Jerry Sandusky-Springer and umpteen shopping channels be propped up by misuse of my dollars to ComCast, AT&T and TimeWarner. Make them be responsible AND have proper accounting.
But that's what it's all about. Proper accounting. The fear of all studios and networks.
