=== Show Development and the 1964 & 1965 World’s Fairs===
Although the Edison Square concept never saw the dawn of day, General Electric was still interested in partnering with Disney. The company approached Walt, and asked him to create an attraction for the 1964 World's Fair in New York. When discussing what the pavilion would be, Walt reached back to his old idea, and once again pitched General Electric on the idea of an electrical progress show. GE loved the idea, and agreed to sponsor the new attraction <ref> http://blog.silive.com/goofy_about_disney/2015/01/disney_goes_to_the_fair_carousel_of_progress_saw_a_number_of_firsts_outside_the_ge_pavilion.html </ref>.

A big advancement in the development of the General Electric attraction was the fact that WED Engineers had finished the Audio Animatronic technology that they had been working on. Although the new technology was not yet perfect, it was good enough to start creating a show, which would eventually become the Carousel of Progress. Imagineers, including Disney legends Roger E. Broggie and Bob Gurr, also devised what they called a "Carousel Theater", a theater which actually rotated clockwise, allowing guests to move on to the next scene without having to stand up <ref> http://modernmouseradio.com/2012/04/19/its-a-great-big-beautiful-tomorrow/ </ref>.
In order to create the characters for the Carousel of Progress, a series of models and voice actors were brought in. The model for the father of the show was actor Preston Hanson, with Rex Allen as his voice. Another model was brought in to pose for the mother, while her voice was done by Rhonda Williams. Casts were made of Disney designer Harriet Burn's arms, which were used for both the mother and the daughter. The son and teenage daughter in the show were based on Disney designer Chick Mill's 8 year old son and 18 year old daughter. Disney Imagineer Richard Irvine's daughter also posed for the teenage daughter role <ref name="Korkis"> http://www.mouseplanet.com/9835/The_Carousel_of_Progress_Cast</ref>.
The robins that sit outside the window in the first scene, were the same robins that Harriet Burns created for Marry Poppins<ref name=Korkis />. The robins came from a Los Angeles museum, and were acquired in exchange for Disneyland tickets. Clarence Nash, the original voice of Donald Duck supplied the Robbins's chirping. [[Image:Carouselwalt.jpg|400px|thumb|Walt Disney showing off his Carousel of Progress|alt= Walt Disney Carousel of Progress]] Walt Disney himself came up with the idea for the family’s dog (he was also the one who suggested the dog change color and breed every scene). Walt was also personally involved in the creation of Cousin Orville, who is seen sitting in a bathtub during the second scene. The character was originally designed by Marc Davis for inclusion in the Edison Square attraction, but it was Walt who modeled his actions (Walt also came up with Orville's dialog as he was acting the character out). The famous voice actor Mel Blank supplied the voice for both Orville and the parrot that can be seen in the first scene. Blaine Gibson, who sculpted all of the characters, said that the grandmother in the attraction was based on his wife's grandmother. Her voice was done by Barbra Luddy <ref name= Korkis />.
The show opened at the 1964 World Fair inside General Electric’s Progressland Pavilion, and it was one of the most visited attractions at the fair. The show consisted of scenes featuring the 1890s, 1920s, 1940s and 1960s<ref> http://www.nywf64.com/genele01.shtml </ref>. The unloading and unloading scenes featured the "kaleidophonic screen" which dazzled guests with various colors. After the show, guests were invited to go to the second floor of the pavilion and see the "Skydome Spectacular". Here, images of nature and energy were projected on the pavilion's domed roof (like a planetarium). The Skydome Spectacular also showcased how GE products were used to help get energy from the sun, and protect the environment.
