The Carousel of Progress is an attraction located at the Magic Kingdom Park at the Walt Disney World Resort, currently operating under the name Walt Disney's Carousel of Progress. Created by both Walt Disney and WED Enterprises as the prime feature of the General Electric Pavilion for the 1964 New York World's Fair, the attraction was moved to Tomorrowland at Disneyland Park in Anaheim, California, remaining there from 1967 until 1973. It was replaced in Disneyland by America Sings in 1974, and reopened in its present home in Walt Disney World Resort's Magic Kingdom in 1975.
Steeped in both nostalgia and futurism, the attraction's premise is an exploration of the joys of living through the advent of electricity and other technological advances during the 20th century via a "typical" American family. To keep it up with the times, the attraction has been updated five times (in 1967, 1975, 1981, 1985, and 1994) and has had two different theme songs, both written by the Sherman Brothers (Disney's Academy Award-winning songwriting team).
Various sources say Walt Disney himself proclaimed that the Carousel of Progress was his favorite attraction and that it should never cease operation. This can be somewhat supported by family and friends, who knew of his constant work on the attraction. Of all the attractions he presented at the 1964-1965 New York World's Fair, Disney seemed especially devoted to the Carousel of Progress.
The Carousel of Progress holds the record as the longest-running stage show, with the most performances, in the history of American theater. It is the oldest attraction not only in the Magic Kingdom, but the entire Walt Disney World Resort. It is the only attraction in Walt Disney World to have a direct physical tie to Walt Disney.
