The document discusses the history and evolution of documentaries. It outlines different modes of documentaries proposed by scholars like Bill Nichols and theorists like John Grierson, who defined documentaries as the "creative treatment of actuality." It also discusses how documentaries have adapted over time, with some critics arguing they have been "dumbed down" for mass audiences, and how different channels like BBC3 have developed distinctive styles to appeal to younger demographics. The author also provides their opinion that John Grierson's view of documentaries representing an interpretation of reality is most accurate, and that no documentary can truly be authentic or objective given that any subject is represented through the filmmaker's perspective.
