What purpose do documentaries serve in mass media?

Documentaries play a crucial role in mass media by informing the public about social issues and promoting awareness. They typically delve into real-life topics, presenting facts and perspectives that encourage viewers to think critically about various subjects, from environmental concerns to social justice. By focusing on factual storytelling and presenting research or interviews, documentaries can highlight underreported issues, educate the audience, and inspire action or change. This informative purpose distinguishes them from purely entertainment-driven media or marketing tools, as well as from fictional narratives that do not adhere to real events or issues. The impact of documentaries often goes beyond mere awareness; they can foster discussion and debate within society, making them a powerful medium for social change.
