Mass communication is the study of how individuals and entities relay information through mass media to large segments of the population at the same time. It is usually understood to relate to newspaper, magazine, and book publishing, as well as radio, television and film, as these mediums are used for disseminating information, news and advertising. Mass communication differs from the studies of other forms of communication, such as interpersonal communication or organizational communication, in that it focuses on a single source transmitting information to a large group of receivers. The study of mass communication is chiefly concerned with how the content of mass communication persuades or otherwise affects the behavior, attitude, opinion, or emotion of the person or people receiving the information.
Mass communication is “the process by which a person, group of people, or large organization creates a message and transmits it through some type of medium to a large, anonymous, heterogenous audience.” [1] Mass communication is regularly associated with media influence or media effects, and media studies. Mass communication is a branch of social science that falls under the larger umbrella of communication studies or communication.
The history of communication moves from prehistoric forms of art and writing through modern communication methods such as the internet. Mass communication fits in when humans began to be able to transmit messages from a single source to multiple receivers. Mass communication has moved from theories such as the hypodermic needle model (or magic bullet theory) through more modern theories such as computer-mediated communication.
In the United States, the study of mass communication is often associated with the practical applications of journalism (Print media), television and radio broadcasting, film, public relations, or advertising. With the diversification of media options, the study of communication has extended to include social media and new media, which have stronger feedback models than traditional media sources. While the field of mass communication is continually evolving, the following four fields are generally regarded to be the major areas of study within mass communication. They exist in different forms and configurations at different schools or universities, but are (in some form) practiced at most institutions that study mass communication.
