The Muppets Show concept does, in retrospect, have a lot in common with SNL, and it got its start as a segment of SNL. Its whole premise revolved around self-reflexive riffing on show-business, something that I think has only become more popular in the Youtube era of Klingon Gangnam style. Whether the exact format of that showbiz satire is still fashionable remains to be seen. It seems like this kind of humor is now most often produced by hobbyists or aspiring internet celebrities.
