History
The desire to increase the visual impact of film has a long history. In 1929, Fox introduced Fox Grandeur, the first 70 mm film format, but it quickly fell from use. In the 1950s CinemaScope (1953) and VistaVision (1954) widened the image from 35 mm film, following multi-projector systems such as Cinerama (1952). While impressive, Cinerama was difficult to install, and the seams between adjacent projected images were difficult to hide.
The IMAX system was developed by Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw.
During Expo 67 in Montreal, Kroitor's In the Labyrinth and Ferguson's Man and the Polar Regions both used multi-projector, multi-screen systems. Each encountered technical difficulties that led them to found a company, initially called "Multiscreen", with a primary goal of designing and developing a simpler approach. The single-projector/single-camera system they eventually settled upon was designed and built by Shaw, based upon a novel "Rolling Loop" film-transport technology purchased from Australian inventor Ronald Jones. Later, when it became clear that a single, large-screen image had far more impact than multiple smaller ones, Multiscreen changed its name to IMAX.
Tiger Child, the first IMAX film, was demonstrated at Expo '70 in Osaka, Japan. The first permanent IMAX was in the Cinesphere at Ontario Place in Toronto in 1971, and is still in operation. During Expo '74 in Spokane, Washington, a very large IMAX screen that measured 90 m × 65 m (300 ft × 213 ft) was featured in the US Pavilion (the largest structure in the expo). About 5 million visitors viewed the screen, which covered the viewer's total vision field when looking directly forward. This created a sensation of motion in most viewers, and motion sickness in some. An IMAX 3D theatre also is in operation near the former Expo 67 site at the "Montreal Science Centre" in the Port of Old Montreal.
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 in 1973. It doubles as a planetarium. The first permanent IMAX 3D theatre was built in Vancouver, British Columbia for Transitions at Expo '86, and was in use until 30 September 2009. It was located at the tip of Canada Place, a Vancouver landmark.
As China is now the second largest market after USA with roughly 25 IMAX theatres located throughout the country, IMAX aims to attract more viewers by decreasing the admission prices in China.

Famous quotes containing the word history:
“Classes struggle, some classes triumph, others are eliminated. Such is history; such is the history of civilization for thousands of years.”
—Mao Zedong (1893–1976)
“If usually the “present age” is no very long time, still, at our pleasure, or in the service of some such unity of meaning as the history of civilization, or the study of geology, may suggest, we may conceive the present as extending over many centuries, or over a hundred thousand years.”
—Josiah Royce (1855–1916)
“History ... is, indeed, little more than the register of the crimes, follies, and misfortunes of mankind.
But what experience and history teach is this—that peoples and governments have never learned anything from history, or acted on principles deduced from it.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
