Mutoscopes were originally manufactured from 1895 to 1909 by the American Mutoscope and Biograph Company, or its licensee Marvin & Casler Co., formed by two of American Mutoscope's founders. In the 1920s the Mutoscope was licensed to William Rabkin who started his own company, the International Mutoscope Reel Company, which manufactured new reels and also machines from 1926 until 1949. The term "Mutoscope" is no longer a registered trademark in the United States.
