This document discusses several media theories: Laura Mulvey's theory of visual pleasure and narrative cinema argues that women are often portrayed as objects for the male gaze in films. Signs and signifiers refers to how physical forms take on meanings through social and cultural contexts. The hypodermic needle theory views media as directly injecting ideas into passive audiences. The two-step flow theory proposes that media effects occur through social discussion of media with opinion leaders. Uses and gratifications suggests that audiences actively select media to fulfill different needs like information, identity, and entertainment.
