This theory argues that audiences actively seek out media to fulfill various social and psychological needs. It identifies four main needs that drive media consumption: surveillance or keeping informed about the world, personal identity through relating to media personalities, personal relationships such as forming parasocial relationships with characters, and diversion or escapism from problems through media entertainment. The theory also discusses Stuart Hall's reception theory, which proposes that media texts encode messages from producers but audiences can decode them in different ways - through dominant, negotiated, or oppositional readings that may not match the producer's intended meaning.
