The animated pinball 1-12 segments had been shown on Sesame Street in the late 70's many times. Then they're shown some times on any episode from the early 80's until Elmo's World came on. During the Elmo's World days, they're shown on Sesame Street very LESS times. #6 was shown on one of the 2000 shows and #8 and #11 were shown last year until I think for this season, they start to disappear. Why did people that work on Sesame Street got rid of them?
