The document discusses several theories of audience perspectives in media studies:
1) Historically, audiences were seen as passive masses directly influenced by media, but now are recognized as diverse individuals who actively interpret media based on their own experiences.
2) Stuart Hall's encoding/decoding model showed that media producers encode intended meanings, but audiences decode meanings based on their own perspectives, which may differ from intended meanings.
3) Uses and gratifications theory views audiences as active in using media to fulfill needs like entertainment, social interaction, identity exploration, and information/education.
4) David Gauntlett's concept of the "pick 'n' mix reader" describes flexible audiences who selectively engage with different aspects of media
