A longtime favorite of children and adults, and a staple of PBS, “Sesame Street” bridges many cultural and educational gaps with a fun program. Big Bird leads a cast of characters teaching children numbers, colors and the alphabet. Bert and Ernie, Oscar the Grouch and Grover are just a few of the other creatures involved in this show, set on a city street full of valuable learning opportunities.
Jim Henson created many Muppet characters for the purpose of appearing on Sesame Street.
