The History Channel used to show programs about history. You could actually learn something on The Learning Channel, and I haven't discovered anything new * lately on the Discovery Channel. I have heard enough about the following topics:
Asteroids and comets hitting the Earth.
How about new footage and topics that weren't inspired by popular movies?
* Isn't that redundant - Aren't all true discoveries new? And while I'm at it - What's up with past history?
