(Yay vote from me) My family and I used to watch Discovery Channel ALL THE TIME. It was almost an educational staple for us. Now that I think about it, I don't remember when we stopped watching it completely. Years ago for sure... It fell out of favor with us, and I'm certain it had to do with the programming not being scientific/educational/enjoyable anymore.
