Audience theories provide frameworks for understanding how target audiences will respond to media texts. These include the hypodermic needle effect theory which posits that audiences passively accept media messages, and two-step flow theory which argues that media messages spread from media to opinion leaders and then to others. Uses and gratifications theory suggests that audiences actively seek out specific media to fulfill needs like diversion, relationships, identity, and surveillance. Reception theory examines how audiences can have preferred, oppositional, negotiated, or aberrant readings of media texts. Cultivation theory looks at the long-term effects of media on beliefs.
