The Discover Channel, TLC, and The History Channel have all significantly gone down hill in terms of educational value over the years. TDC is mostly about crab fisherman and truck drivers in cold climates. TLC is "My very special wedding day." "My very special birth." "My very special family." THC is nothing but HITLER'S SATANIST CONSPIRACY WITH UFO'S DURING WWII. Not that it was ever good but the Travel channel is simply "check out these really over-the-top dishes from all over America!"
I can't really understand why people still see The Discovery Channel as a network for learning or science.
"Astronomy offers an aesthetic indulgence not duplicated in any other field. This is not an academic or hypothetical attraction and should require no apologies, for the beauty to be found in the skies has been universally appreciated for unrecorded centuries."
