The uses and gratifications theory views audiences as actively seeking out specific media to meet certain needs. It focuses on why and how people use media rather than what effect media has on people. Katz, Blumler and Gurevitch identified seven areas of focus for this theory including needs, expectations of media, patterns of exposure, gratification of needs, and consequences. They developed 35 needs that were categorized into cognitive, affective, personal integrative, social integrative, and tension release. Common gratifications identified include information, entertainment, social interaction, and escape from reality.
