This document discusses three main sociological approaches to how audiences interact with and are affected by mass media:
1) The hypodermic syringe theory postulates that media has a powerful direct effect on audiences' attitudes and behaviors by injecting them with messages like a drug.
2) Uses and gratifications theory focuses on how audiences use media to fulfill needs like information, identity, relationships, and entertainment.
3) The decoding approach proposes that media messages can be interpreted and understood differently by various audiences based on their social characteristics and the context.
