Uses & Gratification Theory focuses on why people use particular media and what people do with media rather than what media does to people. It argues that people's needs influence how they use and respond to media. The theory was developed in the 1960s as media researchers became interested in what audiences did with media and how individuals actively consumed media to fulfill different needs and reasons. Blumer and Katz expanded on this theory in 1974, identifying specific purposes audiences may have for media use such as diversion, personal relationships, identity, and surveillance.
