Channel 4 aims to produce documentaries that highlight niche topics, provide international perspectives, and explore British culture. They often focus on very niche subjects through their "Three Minute Wonders" series, which helps expose audiences to new topics. Channel 4 also shows documentaries from international perspectives to give audiences a wider understanding of other parts of the world. Additionally, they produce many documentaries about British culture that can provide deeper dives since British audiences already have familiarity with the topics.
