Walt Disney's Carousel of Progress is a rotating theater audio-animatronic stage show attraction in Tomorrowland at the Magic Kingdom theme park at the Walt Disney World Resort in Bay Lake, Florida just outside of Orlando, Florida. Created by Walt Disney and WED Enterprises as the prime feature of the General Electric (GE) Pavilion for the 1964 New York World's Fair, the attraction was moved to Tomorrowland at Disneyland in Anaheim, California as Carousel of Progress, and remained there from 1967 until 1973. It was replaced in Disneyland by America Sings in 1974, and reopened in its present home in the Magic Kingdom in 1975. Steeped in both nostalgia and (in the past) 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 current with the times, the attraction has been updated five times (in 1967, 1975, 1981, 1985, and 1993), and has had two theme songs, both written by the Sherman Brothers, Disney's Academy Award-winning songwriting team. The Carousel of Progress holds the record as the longest-running stage show in the history of American theater. It is one of the oldest attractions in the Walt Disney World Resort. It is also the oldest attraction at Walt Disney World to have been touched by Walt Disney.

Act 1: Turn of the Century (1900s) The first act is set on Valentine’s Day, "right around the turn of the century". The father of the family, John, is sitting on a wooden rocking chair in his home, his dog, Rover, lying on the floor. He mentions that two brothers in North Carolina are working on a "flying contraption" but comments it will never work, followed by mentions of the new inventions and technological achievements of the day. After he shows off the new technology, he calls to his wife, Sarah, who is ironing in the room to John's right. The two discuss how Thomas Edison
