A documentary is a non-fictional film or video that presents information or tells a story about real people, events, or issues. Unlike fictional films, documentaries are typically focused on conveying factual information and often seek to educate or inform viewers on a particular subject.

Documentaries can cover a wide range of topics, from historical events and political issues to scientific discoveries and personal stories. They may use a variety of techniques to present their material, such as interviews, archival footage, reenactments, animations, and voice-over narration.

Documentaries can be produced for various purposes, including entertainment, education, advocacy, and journalism. They can be found on various platforms, such as television, streaming services, and film festivals.
