The Man

Mass media is communication—whether written, broadcast, or spoken—that reaches a large audience. This includes television, radio, advertising, movies, the Internet, newspapers, magazines, and so forth.
Mass media is a significant force in modern culture. Sociologists refer to this as a mediated culture where media reflects and creates the culture. Communities and individuals are bombarded constantly with messages from a multitude of sources including TV, billboards, and magazines, to name a few. These messages promote not only products, but moods, attitudes, and a sense of what is and is not important. Mass media makes possible the concept of celebrity: without the ability of movies, magazines, and news media to reach across thousands of miles, people could not become famous.
What role does mass media play? Legislatures, media executives, local school officials, and sociologists have all debated this controversial question. While opinions vary as to the extent and type of influence the mass media wields, all sides agree that mass media is a permanent part of modern culture. Three main sociological perspectives on the role of media exist: the limited‐effects theory, the class‐dominant theory, and the culturalist theory.
Limited-effects theory

The limited‐effects theory argues that because people generally choose what to watch or read based on what they already believe, media exerts a negligible influence. This theory originated and was tested in the 1940s and 1950s. Studies that examined the ability of media to influence voting found that well‐informed people relied more on personal experience, prior knowledge, and their own reasoning. However, media “experts” more likely swayed those who were less informed.

Class-dominant theory

The class‐dominant theory argues that the media reflects and projects the view of a minority elite, which controls it. Those people who own and control the corporations that produce media comprise this elite. Advocates of this view concern themselves particularly with massive corporate mergers of media organizations, which limit competition and put big business at the reins of media—especially news media. Their concern is that when ownership is restricted, a few people then have the ability to manipulate what people can see or hear. For example, owners can easily avoid or silence stories that expose unethical corporate behavior or hold corporations responsible for their actions.
Culturalist theory

The culturalist theory, developed in the 1980s and 1990s, combines the other two theories and claims that people interact with media to create their own meanings out of the images and messages they receive. This theory sees audiences as playing an active rather than passive role in relation to mass media. One strand of research focuses on the audiences and how they interact with media; the other strand of research focuses on those who produce the media, particularly the news. http://www.cliffsnotes.com/sciences/sociology/contemporary-mass-media/the-role-and-influence-of-mass-media (2008, 03).
