Audience theory offers explanations of how people encounter media, how they use it, and how it affects them. Although the concept of an audience predates media, most audience theory is concerned with people’s relationship to various forms of media. There is no single theory of audience, but a range of explanatory frameworks. These can be rooted in the social sciences, rhetoric, literary theory, cultural studies, communication studies and network science depending on the phenomena they seek to explain. Audience theories can also be pitched at different levels of analysis ranging from individuals to large masses or networks of people.
