Kinetoscope parlorIn 1894, the first Kinetoscope parlor opened in New York with five machines. For 25 cents, customers looked through a peephole to view a short film. A motorized film loop was threaded around a number of rollers within a wooden cabinet. Thomas Edison invented these early motion picture machines to do "for the eye what the phonograph does for the ear." After several years of effort, by 1892, Edison with W.K.L. Dickson, had invented the "kinetograph" - a camera to take motion pictures. Edison then began producing films to exhibit. The machines sold for $250 each, but within a year, competitors entered the market, and public interest declined sharply. By then, however, the era of projected pictures had already dawned.« |
