This document discusses several theories related to audiences and mass communication, including Uses and Gratifications Theory, Reception Theory, and the Hypodermic Needle Theory. Uses and Gratifications Theory proposes that audiences actively seek out media to fulfill desires like diversion, personal relationships, identity, and surveillance. Reception Theory recognizes that audiences can have negotiated or oppositional readings of media that differ from the intended message. The Hypodermic Needle Theory views audiences as passive receivers of media messages, but it is now seen as too simplistic given more sophisticated modern audiences.
