[1] Horizons originally closed in December 25, 1994, a little more than a year after General Electric had ended its sponsorship of the attraction.

Horizons remained operational until World of Motion's successor, Test Track, was ready to open to the public in early 1999.

[3] It was proposed that Horizons would be the sequel to the Carousel of Progress (located in Tomorrowland at Magic Kingdom), Disney's ride from the General Electric Pavilion at the 1964 New York World's Fair.

No reason was publicly given, but the lack of corporate sponsorship, which happened around the same time of the financial disaster of Euro Disneyland is widely accepted as having played the largest part in the decision.

The McCall mural, The Prologue and the Promise, painted on canvas, was removed prior to demolition and is on display in Disney offices (inaccessible to the public and most cast members).

[citation needed] Horizons began with a section entitled "Looking Back at Tomorrow," showcasing visions of the future as perceived from the era of Jules Verne and Albert Robida through the 1950s.

Afterward came the main part of the ride: visions of futuristic life in a section entitled "Tomorrow's Windows".

Their daughter supervises irrigation robots at the desert farm of Mesa Verde (depicting arid-zone agriculture).

She then talks with her boyfriend over video chat, who is a marine biologist at the Sea Castle research base (depicting ocean colonization).

The only Disney attraction at the time with multiple endings, Horizons then allowed riders to select which path they wanted to take back to the FuturePort: from Brava Centauri, from Mesa Verde, or from the Sea Castle.

As the final part of the ride, guests in their "omnimover" would push a button to select amongst the three choices and would be presented with a 31-second video sequence.

[7] The exit corridor of the ride originally featured the mural The Prologue and the Promise by renowned space artist Robert T.

Also, following the attraction's 2017 refurbishment, a new mural added to the entrance features the space station Brava Centauri orbiting the Earth.

The concrete planter west of the current attraction is a physical remnant of the previous installation where the main sign for Horizons once stood, and reflects the distinctive shape of the original ride building.

The Mesa Verde, Brava Centauri Space Colony, and Sea Castle (said to be located on planet "Praya" for the purposes of tying it into the Star Wars universe) ending sequences are unedited and played in their entirety.
