Uses and Gratifications theory argues that audiences are active in choosing media to satisfy their own needs rather than being passive recipients of media effects. It focuses on what people do with media rather than what media does to people. The theory was developed in the 1960s in response to audiences making choices about what media to consume and for what reasons. Media can fulfill functions like surveillance, entertainment, cultural transmission for individuals and society. Researchers later expanded the theory to include specific purposes audiences may use media for, such as surveillance, personal identity, diversion, and personal relationships.
