The kinetoscope was invented in the United States in 1891 by Thomas Edison and William Dickson. The kinetoscope consisted of a strip of film that was passed rapidly between a lens and an electric light bulb as the viewer looked through a peephole.
Located behind the kinetoscope peephole was a spinning wheel with a narrow slit that acted as a shutter, which permitted a momentary view of each of the 46 frames that passed in front of the shutter every second. The continuous movement of the frames resulted in a lifelike representation of motion. The kinetoscope was first publicly displayed in 1894. The kinetoscope formed the basis for the first equipment used to project motion picture film.
