Cinema 180 history
Fred Hollingsworth III began developing a 70mm film system to be projected onto dome screens in 1974. It was based off developments of a widescreen film process called Cinerama, which debuted in 1952. In 1964, a 360 degree version of Cinerama debuted at the World’s Fair in New York.
This kind of theater was the first such theater to exist for amusement parks. Known as Cinema 180, it was called this because 70mm film was projected onto a 180 degree dome screen. A comparison to this would be IMAX theaters – of course, IMAX was a competitor to the Cinema 180. While IMAX predated Cinema 180, IMAX only started trying to get into the amusement park business because Cinema 180 began opening up theaters in parks.
Such parks included Kennywood Park and Hersheypark – which named theirs Cinema Vision.
Below is a video which provides more detail on the Cinema 180 theaters which appeared at various places around the world.
