Even aside from the Cartoon Network – which may be a result, and not a cause – it seems like there are a lot of animated comedies on broadcast TV these days: The Simpsons, King of the Hill, Family Guy, Futurama and I’m sure a slew more that aren’t occuring to me since I don’t watch any of them.
Back when I was a wee twickster, The Flintstones was (IIRC) on in prime time – but that’s a looooooong time ago. Can’t think of any in the '70s or '80s – then The Simpsons came along.
What can cartoons do that live action can’t?
