Are there rules on how often a network can show adverts?
I rather suspect that there might. Presumably these have changed over the years- i.e. the ad breaks have become longer and more frequent in nature. The prospect of providing a public service over servicing corporate greed would be a welcome thing, no?
There's no rule on how often a network can show advertisements. The general rule is about 15 minutes of advertising to 45 minutes of programming. Less isn't as profitable, more generally costs you viewers (and therefore profit).
If they shortened a few programs to 35 minutes to fill in 10 minutes with advertising, it would cost them viewers. If they took it out of the advertising time, it would cost them advertising money. There's no net even way to give up the time.
