I recently saw the Muppets movie. It's the first time I've ever seen anything on the Muppets.
Then I saw the Cookie Monster, but that he was not in the Muppets movie. I found out that only the original Muppets were in the Muppets 2011 movie, and that the rights for the Sesame Street characters are not owned by Disney, who could not then use the characters.
I see a list of complete Sesame Street muppets but no list of exactly which ones are/are not in Sesame Street.
So how did this split/merge happen? Did someone else create Sesame Street?
Was there bad blood here?
