During [[Expo '74]] in [[Spokane, Washington]], an IMAX screen that measured {{convert|27|*|20|m|ft}} was featured in the 'Environmental Theater' of the US Pavilion, the largest structure in the expo; at the time, it was the largest movie screen in the world.<ref>{{cite book |url=https://archive.org/details/expo74worldsfair0000bowe/ |title=Expo '74 World's Fair, Spokane |first=Dawn |last=Bowers |date=1974 |lccn=74-15913 |publisher=Lawton Printing |url-access=registration}}</ref>{{rp|22;102}} It became the first IMAX Theatre to not be partnered with any other brand of movie theatres. About five million visitors viewed the short film ''[[Man Belongs to the Earth]]''. Because the screen covered the viewer's total visual field when looking directly forward, most felt a sensation of motion and some experienced [[motion sickness]].<ref name=Sommerfeld24>{{cite news |url=https://www.inlander.com/culture/expo-74s-featured-the-biggest-movie-screen-on-the-planet-imax-27885953 |title=Expo '74 featured the biggest movie screen on the planet — IMAX |first=Seth |last=Sommerfeld |date=May 2, 2024 |work=Inlander |access-date=18 December 2024}}</ref>

The large pavilion screen was torn down after the exposition closed and was replaced by a nearby permanent IMAX theater which opened in 1978 and was demolished in 2018;<ref name=Sommerfeld24/> however, its screen size is less than half. Due to protests, the City of Spokane officials decided to work with the IMAX Corporation to demolish the 1978 theatre, under the condition they renovate the former US Pavilion itself into IMAX's first permanent ''outdoor'' giant-screen theatre. The plan was to use material on the inside of the structure similar to that used when first constructed. However, it was expected to last only five years, due to weather conditions destroying previous materials.<ref>{{cite web |url=http://www.spokesman.com/stories/2016/sep/30/imax-theater-in-riverfront-park-headed-for-demolit/ |title= Imax theater in Riverfront Park headed for demolition; the fate of pavilion rides still in question |publisher= The Spokesmen-Review |date= Sep 30, 2016 |access-date= May 24, 2017}}</ref> Concept art has been released in videos featured on Spokane's renovation site, and its budget revealed that seating is planned for more than 2,000.<ref>{{cite web |url=http://riverfrontparknow.com/redevelopment/u-s-pavilion-shelters/ |archive-url=https://web.archive.org/web/20160216021903/http://riverfrontparknow.com/redevelopment/u-s-pavilion-shelters/ |url-status=dead |archive-date= February 16, 2016 |title= US Pavilion & Shelters |publisher= City of Spokane |access-date= May 24, 2017 }}</ref><ref>{{cite web |url=https://static.spokanecity.org/documents/parksrec/aboutus/planning/2014-riverfront-park-master-plan.pdf |title=2014 Riverfront Park Master Plan |publisher= City of Spokane |access-date=June 1, 2017}}</ref>

The first permanent IMAX Dome installation, the Eugene Heikoff and Marilyn Jacobs Heikoff Dome Theatre at the [[Reuben H. Fleet Science Center]], opened in [[San Diego]]'s [[Balboa Park, San Diego, California|Balboa Park]] in 1973. It doubles as a [[planetarium]] theater. The first permanent IMAX 3D theatre was built in [[Vancouver]], British Columbia, for ''[[Transitions (film)|Transitions]]'' at [[Expo '86]], and was in use until September 30, 2009.<ref>{{cite web |url=http://www.imax.com/vancouver/ |title=IMAX Theatre |publisher=Imax.com |date=October 1, 2009 |access-date=July 3, 2010}} (official site).</ref> It was located at the tip of [[Canada Place]], a Vancouver landmark.
