There is no history on the History channel. There's nothing true on TruTV. There's no music on music television. There's no science on the science channel.
Man I love Spacetime and Eons. I have watched almost all of spacetime. I wish there were a spacetime hardcore where they threw as much math at me as possible. Awesome channels
So true. PBS has always been a reliable place to find something decent to watch when all else fails I feel. Not to mention no commercials! or very little if any.
