There are programs that are great like LIFE, Planet Earth, Earth: The Biography, The Universe, America: The Story of Us, How Stuff Works, Mythbusters(to an extent, sometimes it's useless), etc... but they are few and far between.

You get allot more then that in the UK, loads more, there's so many programs to watch and learn stuff from here on the discovery channels, history, and military channel. I don;t like Myth busters though.
