First of all, there are 4000+ episodes of Sesame Street. Maybe it can be on a few more times per day. Or they can by the ones from Noggin (Unpaved and 1-2-3) and unedit them! As for the cartoons, there was only one season of the animated Fraggle rock, so it should be on weekends. Little Muppet Monsters, I'm not sure about. The animated versions of Pigs in Space and Kermit P.I. (and others that are unknown) only had about two episodes total!
But here's my two cents....
There could have been a Henson (muppet) channel if it wasn't for Hallmark. Some fans had to push screaming and angrerd just for them to put ALF back on (provided it's still on) All they have now are B- List Filmation shows and programing that would make Lifetime look like Tim Allen from Home Improvement. I think a Henson channel would be an excellent idea, and trounce them in the ratings.
(P.S. am I the only one that thinks that there are too many Home Shopping Channels?)
