Sesame Street first aired on 180 PBS stations on November 10, 1969, using Jim Henson's puppets to teach letters, numbers and colors. The show was created by Joan Ganz Cooney and Lloyd Morrisett and produced by their Children's Television Workshop. Good News Network noted that the program's goal was to prepare less advantaged children for school, and that by 2009 it had been translated into many languages.
