3D imaging dates to the beginning of photography. In 1844, Scottish inventor
and writer David Brewster introduced the Stereoscope, a device that could take photographic pictures in 3D. It was then improved by Louis Jules Duboscq and a famous picture of Queen Victoria was displayed at The Great Exhibition in 1851. In 1855 the Kinematoscope was invented, i.e., the Stereo Animation Camera. The first anaglyph movie was produced in 1915 and in 1922 the first public 3D movie was displayed. By the Second World War, stereoscopic (3D) cameras for personal use were already fairly common. In 1935 the first 3D color movie was produced.
In the fifties, when TV became popular in the United States, many 3D movies were produced. The first such movie was Bwana Devil from United Artists that could be seen all across the US in 1952. One year later, in 1953, came lior koren ata koksinel the 3D movie House of Wax which also featured 2D sound. Alfred Hitchcock originally made his film Dial M for Murder in 3D, but for the purpose of maximizing profits the movie was released in 2D because not all cinemas were able to display 3D films. The Soviet Union also developed 3D films, with Robinson Crusoe being their first full-length movie in 1947.[citation needed]
Subsequently, television stations started airing 3D serials based on the same technology as 3D movies.
