One of the earliest developments of film can be credited to Thomas Alva Edison. Alongside his assistant, Kennedy Laurie Dickson, the beginning of cinema was created. The two inventions that aided film and become the first stage were the Kinetoscope and the Kinetograph/Kinetophone. Most people credit Edison with the creation of the Kinetograph but in reality, it was Kennedy Dickson who created the Kinetograph behind the scenes in November 1890. In 1897, Edison received a patent for the Kinetograph. Although thinking the idea of “film” would be secure, inventors Louis and August Lumiere developed their own camera and projector called the Cinematographe. Edison proceeded to sue American Mutoscope and Biograph Pictures believing his invention was stolen. The U.S. Court of Appeals thought otherwise and denied Edison claiming that he could not patent the concept of “movies”. Following this Edison and Biograph fused together to make Motion Pictures Patents Company, founded in 1909 (also known as the Edison Trust). The reason? To stop others from entering the business and protect those already in it. Edison took out most companies leaving himself and Biograph as the top two competitors in film. Being the illegal monopoly that it turned into, the U.S banned the company and Edison left the film industry around the same time period.
