For some reason I can't access the article at the moment but, when I was in radio and TV, years ago, the FCC restricted how many advertising minutes you could run in an hour or per show. I want to say that, in radio, you couldn't go over 13 minutes in any hour but few dared to approach that limit except the kiddie rock-n-roll stations lest they turn away listeners. iirc, that ruling has been removed.
