references to General Electric's passé "Medallion Home" campaign were dropped; and Father from "The Home of the 1940s" now sat on a bar stool rather than on the kitchen nook bench. After the show, guests boarded an inclined moving walkway to the building's second level, where a 4-minute post-show, narrated by Mother and Father (with a few barks and growls from their dog) coincided with a view of an enormous animated model of Progress City, based on Walt Disney's original concept for Experimental Prototype Community of Tomorrow (EPCOT) and the Walt Disney World property. As the 1970s rolled in, the Carousel of Progress saw dwindling audiences. GE thought they were not getting the most for their advertising dollars, surmising that 80% of the people that saw the attraction were Californians who had seen it many times. GE asked Disney to move the show to their new Magic Kingdom at Walt Disney World. The Disneyland show closed on September 9, 1973, and was packed up for Florida. The Progress City model was disassembled and portions of the center of it were reassembled in Florida. Disneyland soon incorporated The Carousel Theater into its plans to celebrate America's Bicentennial. In 1974 it was filled with a new show called America Sings, a salute to American music. It closed in 1988, and was not replaced for ten years. Innoventions, a version of the popular Epcot attraction of the same name, opened there with the New Tomorrowland in 1998, using a stylized rendition of "There's a Great Big Beautiful Tomorrow" as its theme song. The building was then redesigned and reopened in 2015 as the Tomorrowland Expo Center, hosting the Star Wars Launch Bay. Magic Kingdom Carousel of Progress opened in the Magic Kingdom's Tomorrowland on January 15, 1975, alongside Space Mountain, under a 10-year sponsorship contract with General Electric. Unlike the small changes that occurred when the show moved from the 1964–1965 New York World's Fair to Disneyland, extensive changes were made. A new carousel theater building was designed to house the attraction: a one-story pavilion, with a loft above it used by the Tomorrowland Transit Authority PeopleMover track, wrapping around the building's north side. The interior and exterior of the building received new color schemes, with blue and white stripes that grew smaller and larger as the building turned. The theater also now rotated counterclockwise, rather than clockwise like the two former theater
