Sesame Street, whose opening theme song and cast of characters are familiar to generations of children, is turning 40. The show premiered on November 10, 1969. A fitting tribute to the show's mission is a recent study that found teens who watched Sesame Street in pre-school had higher grades than those who did not. And the show is still going strong as it enters it's 40th year. Last season, Sesame Street averaged more than 5 million viewers each week. WTCI is proud to be the home of Elmo, Big Bird, Cookie Monster and the whole fuzzy gang here in the Tennessee Valley. Congratulations Sesame Street and Happy 40th!
