Uses and gratifications theory
Uses and gratifications theory is a communication theory that describes the reasons and means by which people seek out media to meet specific needs. The theory postulates that media is a highly available product, that audiences are the consumers of the product, and that audiences choose media to satisfy given needs as well as social and psychological uses, such as knowledge, relaxation, social relationships, and diversion.
Uses and gratifications theory was developed from a number of prior communication theories and research conducted by fellow theorists. The theory has a heuristic value because it gives communication scholars a "perspective through which a number of ideas and theories about media choice, consumption, and even impact can be viewed".
