The history of documentary film began in 1895 with the Lumiere brothers' invention of the motion picture camera. Early documentary films from this era were called "Actualities" and simply captured short, unedited scenes. The documentary style as we know it today emerged in 1922 with Robert Flaherty's Nanook of the North, which was the first feature-length factual film to use creative interpretation and staged scenes. In the 1930s, John Grierson further developed the poetic realist approach to documentary filmmaking. Direct Cinema emerged in the 1950s-1960s in the U.S., aiming to present events directly and unmediated. Mockumentaries also began in the 1960s, using documentary codes and conventions to trick audiences
