 Like Thomas Edison's Kinetoscope the Mutoscope did not project on a screen, and provided viewing to only one person at a time.Cheaper and simpler than the Kinetoscope, the system marketed by the American Mutoscope Company quickly dominated the coin-in-the-slot "peep-show" business.The Mutoscope worked on the same principle as a flip book, with individual image frames printed onto flexible cards attached to a circular core which revolved with the turn of a user-operated hand crank.
