In 1877, Thomas Eddison invented the Phonograph. It recorded and played back sound etched on a wax cylinder. He wanted to use his Phonograph in conjunction with the Zoopraxiscope. The Zoopraxiscope projected moving images. This was invented by Eadweard Muybridge. The first moving images showed the motion of a galloping horse. Eddison wanted to add audio to moving pictures for large theatres. The main problem that faced Eddison was that he was unable to amplify the sound. Phonographs projected their sound through large horns. Even with the use of these horns the amplitude was not enough for large theaters. Because of this Muybridge discarded the idea. (Filmmaker IQ, 2014) Eddison believed that the future of cinema relied on a coin operated machine
