This document outlines several types of documentaries: docusoaps which follow groups over time in an observational style; reality TV which blends authentic footage with commercial elements; fly on the wall documentaries where subjects ignore the camera; mixed documentaries that use interviews and archived footage; self-reflective documentaries where the subject is aware of the camera; docudramas that reconstruct past events; and fully narrated documentaries where a voiceover guides the story. It also discusses current affairs programs that explore issues in more depth than news but require faster production than documentaries.
