Goes Video in 1989, and concentrated on home video releases, but returned to its original title in 1991. PBS continued to broadcast the program until the fall of 1996, when it was cancelled due to a lack of underwriting. In popular culture In the early-to-mid eighties to the early nineties, Sesame Street had a recurring parody sketch, "Sneak Peek Previews", which illustrated differences of opinion. In a run-down movie theater, Oscar the Grouch and Telly Monster together watched a short video segment, usually from the Sesame Street archives. After the video, Oscar invariably disliked it, and Telly enjoyed it, and they each told why. Siskel and Ebert appeared in one sketch in 1991 in which they instruct the hosts on how their thumbs up/thumbs down rating system works. At the end of sketch, Oscar asks if there could be a thumbs sideways ratings, and goads the two men about whether or not that would be acceptable, as Ebert likes the idea, but Siskel does not.
