The mutoscope was a peep show-style movie viewer that was first manufactured by the American Mutoscope and Biograph company, and is notable for being one of the first means by which motion pictures were exhibited. The company gradually changed its focus to motion picture production and projection, and by the early 1920s, had stopped production of both mutoscopes and the movie reels that were played by the machines. The company also produced arcade photo booths under the name of "Photomatic".
