This document discusses Uses and Gratifications theory, which examines why people use media. The theory argues that people's needs influence how they use and respond to different media. It became apparent in the 1960s that audiences actively consume media for different reasons. Laswell suggested in 1948 that media served entertainment, correlation, surveillance, and cultural transmission functions. Blumer and Katz expanded on this in 1974, stating that people may expose themselves to media for diversion, personal relationships, identity, and surveillance. Uses and gratification theory suggests that media users actively choose and use media to fulfill their own needs and goals.
