This document summarizes several theories of audience reception of media: - The hypodermic needle model suggests media directly injects opinions into passive audiences' minds, exemplified by Nazi propaganda. It is now obsolete as audiences are more active. - Uses and gratifications theory proposes audiences seek to fulfill needs like surveillance, identity, and diversion through media consumption. - Encoding/decoding theory describes how institutions encode messages while audiences decode based on their own interpretation, which can differ due to age, culture, etc. - Social and cultural context theory holds that audiences' interpretations vary according to their social position, culture, class, gender, and preexisting knowledge.
