Elmo's World celebrates 35 years of Sesame Street. Elmo wants to know more about the street he lives on, so Grover takes him on a trip back in time to see what Sesame Street was like before Elmo was born.
This one-hour special marks the 20th anniversary of Sesame Street, the ground-breaking educational children's series that has taught numbers and the alphabet, along with social and cultural concepts, to generations of preschoolers.
