For 45 years we have been singing about Sunny days on this Street where Bert and Ernie along with Gordon and Susan and Big Bird live. Sesame Street turns 45 and the show that featured Jim Henson’s Muppets debuted on November 10th in 1969 and in 1973 was competing with one other big time children’s show now Sesame Street competes with over 84 shows geared for preschoolers.
