Uses and gratifications theory posits that people actively seek out media to fulfill certain needs. Rather than focusing on how media affects people, UGT examines why and how people consume media. It takes an audience-centered approach to understand mass communication and what motivates people's media use. Romantic comedies aim to provide viewers with an idealized view of relationships that allows them to escape reality, while horror films elicit physical and psychological reactions from audiences by confronting fears and testing their courage. Filmmakers can manipulate sounds and music to influence the emotions and tension felt by viewers based on the genre.
