Muppets tonight aired on ABC, and Disney has distributed the films since the 90's, but that was years before Disney owned the characters. (The original deal fell apart because they wanted the Sesame Street characters too, and that was a deal breaker for Jim.) The Henson library is so split up now, Kermit has been edited out of vintage tv specials Disney didn't get in the deal. The Jim Henson Hour may never see a video release in it's original aired form, because Disney doesn't own the Storyteller series that comprised the second half of the show. That's how messed up things have become thanks to Disney.
Henson's non Disney puppet projects in the past few years do not use the Muppet name at all, even though the style of the puppets is unmistakeable.
I used to follow the Muppet fandom more closely, and Disney's handling of the characters did not sit well with many. The plan to hire and train multiple groups of performers for Kermit and the gang to entertain on the Disney cruise ships was regarded as cheapening the characters. It also went against the tradition of one performer for a character in all appearances no matter the venue. Muppeteers usually aren't replaced unless they retire or have passed away.
The Muppet film that came out a couple years back seems to be a step in the right direction though.
