This document discusses several audience theories that can be used to understand how audiences interact with media. It describes uses and gratifications theory, which suggests that audiences actively use media to fulfill needs like diversion, social interaction, identity, and surveillance. Reception theory holds that encoded meanings in media can be given dominant, negotiated, or oppositional readings by audiences based on their social and cultural backgrounds. Finally, the effects and hypodermic models are mentioned, which propose that media have powerful influences over passive audiences, though uses and gratifications theory argues audiences are active.
