Documentaries aim to portray real events and situations to audiences. They can cover topics like politics, history, and culture. While some documentaries only use factual footage, others may include reconstructions if real evidence is unavailable. John Grierson is credited with coining the term "documentary" in the 1920s and focused on portraying factual information. More recently, some argue documentaries have become more creative in their storytelling and less focused solely on facts. Key elements of documentaries include observations, interviews, dramatizations, mise-en-scene, and exposition. However, it is debated how much documentaries can truly capture reality or truth given creative choices that are made.
