Uses and Gratifications Theory examines how audiences actively engage with media to fulfill various needs. It was developed by Blumler and Katz who argued that people's social and psychological origins generate expectations of media that lead to differential exposure patterns fulfilling needs and other consequences. The theory suggests that media use fulfills cognitive needs for knowledge, affective needs for emotion/pleasure, personal integrative needs for status/self-esteem, and social integrative needs for social interaction. The internet has expanded media options and allowed audiences more control over fulfilling these needs.
