These inventions laid the foundation for the development of the movie industry. The automobile industry was more influenced by inventors like Karl Benz. The communications industry had earlier contributions from people like Samuel Morse (telegraph) and Alexander Graham Bell (telephone) before Edison's major impact. The mass transit industry was influenced by various engineers and inventors in the areas of railroads and streetcars, not primarily by Edison.
