It all started in 1969 with a simple idea: Can television be used to get kids ready for school? 50 years later, Sesame Street is an educational force for change that's seen in over 150 countries around the world. Sonia Manzano (“Maria” from Sesame Street), Matt Vogel (Big Bird and the Count, Sesame Street puppet captain and director), Eric Jacobson (Grover, Bert and Oscar), Ryan Dillon (Elmo), and Dr. Rosemarie Truglio (SVP, Sesame Workshop Content and Curriculum)-with special appearances by some fuzzy and feathered friends-will talk about Sesame Street's legacy and future.
