In other words, mass communication refers to the imparting and exchanging of information on a large scale to a wide range of people. It is usually understood to relate newspaper, magazine, and book publishing, as well as radio, television and film, even via internet 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 number 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.
