The document discusses three major audience theories: 1) The effects/hypodermic model views audiences as passive recipients who are directly influenced by media messages. It suggests media can negatively impact behavior. 2) Uses and gratifications theory sees audiences as active, using media to meet needs like information, identity, and social interaction. Power lies with audiences who choose what to accept. 3) Reception theory examines how producers encode meaning in media and how audiences can decode it in dominant, negotiated, or oppositional ways based on their own views. It gives audiences more agency than the effects model.
