20th century film The Birth of a Nation
Throughout the early 20th century, screen artists continued to learn how to work with cameras and create illusions using space and time in their shots. This newly introduced form of creativity made way for a whole new group of people to be introduced to stardom, including David W. Griffith, who made a name for himself with his 1915 film, The Birth of a Nation. In 1920, there were two major changes to the film industry: the introduction of sound and the creation of studio systems. In the 1920s, talent who had been working independently began joining studios and working with other actors and directors. In 1927, The Jazz Singer was released, bringing sound to the motion picture industry.
