Omnivision started in [[Sarasota, Florida]]. Theatres were designed to compete with Omnimax but with much lower startup and operating costs. Most theatres were built in fabric domed structures designed by Seaman Corporation. The last known OmniVision theatres to exist in USA are The Alaska Experience Theatre in [[Anchorage, Alaska]], built in 1981 (closed in 2007, reopened in 2008), and the Hawaii Experience Theatre in  [[Lahaina, Hawaii]] (closed in 2004). [[Rainbow's End (theme park)]] in NZ had the only remaining permanent Cinema 180 attraction until May 2015 when it was demolished.
 
One of the few producers of 70&nbsp;mm films for Cinema 180 was the German company Cinevision (today AKPservices GmbH, Paderborn).
