That basically IS it Jerry. Overhead in the form of talent salaries and operational costs take huge amounts of money though. The ability to demonstrate ratings factors into what these companies can charge for ad time also.

Radio stations are almost ALL owned by just a handful of broadcast corporations. Broadcast companies like Premiere Radio Networks (Rush Limbaugh) are still going broke despite his popularity... mainly because of his exhorbitant salary.

Air America had financial difficulty due to the fact that their overhead was much higher than the amount of money they were bringing in through ad sponsors.

This consolidation (and control) of the ownership of the PUBLIC airwaves (they belong to WE the People) is what Mark Lloyd's plan is trying to combat.

WHY should just a few private corporations control ALL of what we see, hear and read?
