The document discusses audience theory and how audiences interact with media texts. It describes several models of audience theory:
1) The hypodermic needle model from the 1920s which suggests audiences passively accept media messages.
2) The two-step flow model which challenges the hypodermic needle model by suggesting information flows from media to opinion leaders and then to other groups.
3) Uses and gratification theory which says individuals use media actively to fulfill different needs like diversion, social interaction, identity, and information.
4) Reception theory looks at how audiences interpret media texts based on their demographics and psychographics.
