What do you mean by mass …

Mass media consists of the various means by which information reaches large numbers of people, such as television, radio, movies, newspapers, and the Internet. Sociologists study mass media especially to see how it shapes people's values, beliefs, perceptions, and behavior. For example, mass media contributes to socialization, including gender socialization, as when movies implicitly teach young people that it is wrong for females to have many sexual partners. Mass media also affects social movements; for example, news coverage of the U.S.-Vietnam War helped spark the 1960s anti-war movement. Another topic is the relation between media and social power. For example, if mass media powerfully influences beliefs and behavior, and it is controlled by relatively few individuals, those individuals have significant power even in democratic societies.
