Tom,
I agree with you. The entire broadcast system is dumbing down, and attempting to drag us with it. You used to be able to tune into DIY and learn how to build, refurbish, or maintain things; there was an aircraft channel where they actually had shows that showed aviation tech items, but they showed aviation vacations, history, and even building your own aircraft (this is the network that became the Military Channel); and you could find stations of all kinds of other interests that actually taught you. Today nearly everything is becoming an over drama soaked cuss fest and short time limits to do stuff. Larry Potterfield is still trying to teach us in is advertising, but he needs to do it in a promotional format, because they won't build an entire show around it.
If broadcast media claims that we are too deep into our podcasts and dvd's it is only because they forced us to go that way!
