Behind the scenes on Sesame Street

A TV show for young children, Sesame Street aimed to educate and promote tolerance at the same time. It was first broadcast in 1969 and went on to become one of the most popular children's shows ever made. Sonia Manzano starred as Maria on Sesame Street for 44 years and she has been speaking to Ned Carter Miles about how the show's ethos shaped its characters and storylines.
