Question: Why do people watch documentaries? What pleasures are available to viewers?
I think people generally watch documentaries to be educated and informed. Additionally most people watch documentaries about themes they are interested in so it is also their pleasure and they do that do be entertained or to escape from their daily troubles. Another reason for some people to watch documentaries is to enable themselves to socially interact.
For example my brother often watches documentaries about sharks, like “Der weiße Hai- Täter oder Opfer?” or “Planet Erde-Wasserwelten”, to escape from an exhausting school day and because he is really interested in sharks and wants to be educated and informed about them. It also allows him to socially interact because most of his friends are interested in things like that, too.
