John Grierson coined the term "documentary" in 1936 to describe films that document real people and events. A documentary uses actual footage or narration to reconstruct and present factual information about social issues and invite audiences to draw their own conclusions. Central to the genre is focusing on and questioning real individuals and situations in a social context so viewers can form opinions on what they see. Documentaries are presented as factually accurate through labeling and context that lead audiences to believe the people and events are real.
