what is mass communication

Mass Communication is the term used to describe the academic study of various means by which individuals and entities relay information to large segments of the population all at once through mass media.

In the United States, many university journalism departments evolved into schools or colleges of mass communication or "journalism and mass communication," as reflected in the names of two major academic organizations. In addition to studying practical skills of journalism, public relations or advertising, students also may major in "mass communication" or "mass communication research." The latter is often the title given to doctoral studies in such schools, whether the focus of the student's research is journalism practice, history, law or media effects. Departmental structures within such colleges may separate research and instruction in professional or technical aspects of newspaper and magazine publishing, radio, television, and film. Mass communication research includes media institutions and processes, such as diffusion of information, and media effects, such as persuasion or manipulation of public opinion.
