"Commercial motion pictures were invented at the Edison Laboratory between 1888 and 1893. Perhaps none of the component parts were strictly new, but the ability of Edison and his staff to reorganize them for a specific purpose was an extraordinary cultural achievement. In 1894, Edison was the sole producer of motion pictures in the world. This fourth disc of a four disc set contains films produced between 1914-1918."@en . . . . . . . . . . .
