The document discusses several theories related to how media affects audiences:
- The hypodermic needle theory suggests media has a direct effect on audiences by "injecting" ideas and behaviors, but it is an oversimplified view.
- Cultivation theory proposes that repeated exposure to media shapes peoples' perceptions of reality over time, even for light viewers, by reinforcing mainstream values.
- Reception theory focuses on the active role of audiences in interpreting meanings from media texts based on their own experiences and contexts, rather than meanings intended by producers. Different audiences can derive different readings from the same text.
