On This Day in History: Sesame Street Debuts

On this day in 1969, "Sesame Street," a pioneering TV show that would teach generations of young children the alphabet and how to count, makes its broadcast debut. "Sesame Street," with its memorable theme song ("Can you tell me how to get/How to get to Sesame Street"), went on to become the most widely viewed children's program in the world. It has aired in more than 120 countries.

From the show's inception, one of its most-loved aspects has been a family of puppets known as Muppets. Creator, Joan Ganz Cooney hired puppeteer Jim Henson (1936-1990) to create a cast of characters that became Sesame Street institutions, including Bert and Ernie, Cookie Monster, Oscar the Grouch, Grover and Big Bird.
