What happened to all of the educational channels?

I know what happened..
It's not really a mystery why the US is last in just about every aspect of education.
They would rather watch Honey Boo Boo and other train wrecks than educational programs, so they feel better about themselves.
And strangely the TLC (The LEARNING channel), is the one broadcasting the aforementioned show because it provides revenues through ratings.

But PBS still runs NOVA, and the new series of Making Stuff with David Pogue has been pretty good so far.
My long time favorites are Mythbusters and Through the Wormhole with Morgan Freeman.

I bet there's a few Americans who could pass a CLEP about Honey Boo Boo.
