Documentary films have taken many forms since their early beginnings as factual records of events without creative storytelling. Key developments include Robert Flaherty's 1922 film Nanook of the North being considered the first documentary with a narrative, the use of propaganda films during World Wars I and II, the direct cinema movement in the 1960s capturing live events without interference, and contemporary documentaries that explore social and political issues through interviews. Documentaries have evolved from simply recording actualities to utilizing diverse styles and storytelling techniques to examine a wide range of topics.
