IMAX Corporation is a movie-theater company noted for its vivid in-theater experience, thanks to 3D effects and huge screens. Movies with intense special effects, such as Avatar or Iron Man, are particularly popular in IMAX screens. IMAX is also known for creating the largest movie screen in the world, a roughly eight-story behemoth in Sydney, Australia. Roughly a billion people have watched a film in an IMAX theater in the past four decades. Typically, an outside theater company like AMC or Regal, both of whom have strategic relationships with IMAX, has one or two IMAX screens among the 12 or 16 it operates in a given location.

The IMAX Corporation developed the IMAX movie standard, which couples 70mm film with six audio channels. IMAX movies are generally played on huge flat screens, special dome screens or curved screens designed for 3D IMAX movies.HowStuffWorks: How IMAX WorksMovie-Info: What is IMAX?

At the 1967 International and Universal Exposition (EXPO '67), people were awed by multi-screen films. These films were shot on multiple cameras and then played back on multiple projectors to create one really big movie. Soon after, some of the filmmakers who had made the multi-screen movies developed the 70mm IMAX format we know today. IMAX technology premiered at EXPO '70 and in 1971 the first IMAX theater was opened in Toronto, Canada.IMAX.com: Corporate Profile
