The document discusses several theories about the effects of media on audiences:
- Early theories saw the media as having a direct influence on audiences' behaviors, but later theories found audiences are not passive and interpret media through their own experiences.
- Uses and gratifications theory found audiences are active and use media to fulfill various needs like information, entertainment, social interaction, and identity formation.
- Cultural effects theories suggest that while media may not directly influence people, constant exposure to limited perspectives could create unconscious biases over time. However, audiences still interpret media through their own cultural lenses.
