Question: What year did General Electric leave Horizons?
About the article "Epcot", section "Corporate sponsorships".

Candidate passages:
Horizons was the name of a dark ride attraction at Epcot (then known as EPCOT Center), a theme park at Walt Disney World in Lake Buena Vista, Florida USA.
Located on the eastern side of the "Future World" section of Epcot, the attraction used Disney's Omnimover conveyance system, which took guests past show scenes depicting visions of the future.
It is believed to be the sequel to Walt Disney's Carousel of Progress, an attraction in Tomorrowland at Walt Disney World's Magic Kingdom.
Horizons was the only attraction in "Future World" to showcase all of Epcot's "Future World" elements: communication, community interaction, energy, transportation, anatomy, physiology, along with man's relationship to the sea, land, air, and space.
The attraction officially opened on October 1, 1983, as part of Phase II of Epcot.
Horizons originally closed in December 1994, a little more than a year after General Electric had ended its sponsorship of the attraction.
Horizons temporarily re-opened in December 1995 due to the closure of two other attractions that were down for refurbishment in "Future World", Universe of Energy and World of Motion.
The attraction permanently closed on January 9, 1999, after which the attraction was dismantled and its structure demolished to make room for , a motion simulator thrill ride that opened on October 9, 2003.

In 1827 The Duke of Wellington granted Sabine general leave of absence from the army on the understanding "that he was usefully employed in scientific pursuits."
But his leave did not last very long.
Political agitation in Ireland necessitated an increased military presence in the country, and in 1830 Sabine was recalled to military duty.
He remained in his native land for the next seven years, but he did not allow his new military duties to interrupt his scientific endeavours.
He continued his pendulum investigations and in 1834 commenced a systematic magnetic survey of Ireland – the first of its kind in what was then the United Kingdom.
It was extended to Scotland in 1836, and to England the following year. 
"Horizons", in its concept phase, was named Century 3 (or Century III), to recognize the third century of American existence (1976–2076).
The name was changed to Futureprobe to help appeal the attraction toward international guests who wouldn't understand or appreciate "Century 3".
In the end, the "Futureprobe" name was scrapped due to the medical connotation of the word "probe".
After much debate, GE and Disney officials settled on the name Horizons.
Prior to the start of construction, the project's budget was slashed by $10 million (USD).
The building size was reduced and the length of the ride was shrunk by 35%, shortening the ride length by .
Horizons opened exactly one year after Epcot opened and was located between World of Motion and the Universe of Energy.
The Wonders of Life pavilion became Horizons' new neighbor in 1989, and World of Motion closed in 1996.
Horizons remained operational until World of Motion's successor, Test Track, was ready to open to the public in early 1999.
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.
As the Carousel of Progress followed the changes in lifestyle that faced a family as they lived through the 20th century, Horizons continued their story, showing how they might live in the 21st century.
The Carousel's theme song "There's a Great Big Beautiful Tomorrow" was part of the Looking Back at Tomorrow portion of Horizons.
The version of "There's a Great Big Beautiful Tomorrow" that could be heard in Horizons coming from a television in the Art Deco scene is the exact version that can still be heard on a radio during the first act of the present Carousel of Progress.
The original ride concept came from Reginald Jones (then–CEO of GE) and Jack Welch (future CEO of GE).
The concept was to focus on Thomas Edison and his body of work along with the origin of General Electric; it was changed to focus on the future of America, a theme that changed yet again to respect that Epcot was to appeal to a global audience.
The building which housed Horizons was designed to resemble a spaceship, while accentuating the third dimension and giving the impression of an infinite horizon.
During the early 90s, after GE had dropped sponsorship, some ideas were tossed around about the pavilion being turned into a space-themed pavilion.
The building would have been upgraded and rethemed.
The ride system would be changed drastically, in which the guest would be in an individual space harness while viewing space stations and space in general and would control the pitch and yaw of the vehicle.
On January 9, 1999, Horizons closed permanently.
No reason was publicly given, but the lack of corporate sponsorship probably played a large part in the decision.
It is also claimed that a reason for the attraction closing was major structural problems (a large marshland sink-hole underneath the structure which emerged in 1998), along with problems with the roof.
The building was claimed to have been close to collapsing under its own weight.
The building stood unoccupied for well over a year as Disney decided between either relaunching the attraction (which would have required a new storyline and major building renovation and upgrades) or demolishing the building and creating a new attraction in its place.
It was decided to build a new cutting-edge outer space-themed attraction, so the Horizons building was slowly torn down in July 2000.
The demolition of the building marked the first time in Disney history that an entire ride building had to be demolished in preparation for a new attraction.
Construction on began in late 2000 and the new attraction opened in 2003.
Various props from Horizons have been displayed around Walt Disney World and even in Walt Disney Studios Park at Disneyland Resort Paris.
A display that features the butler robot animatronic was set up in "EPCOT: Creating the World of Tomorrow" for Epcot's 25th anniversary.
At Disney's Hollywood Studios, a few of the props from the underwater city scene are displayed in one of the studio warehouses.
And one of the Desert ships has made its way to Disney's Hollywood Studios, hanging from the ceiling of a restaurant.
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).
