This textbook describes various ways of studying, and competing accounts of, the media's influence. The effects themselves, and the reasons behind the media's influence, are also considered. Chapters discuss scientific approaches, the role of the scientific method, the history of media effects research, media violence, sexual content, frightening media, persuasion, news reports and politics, stereotypes, the impacts of new technologies, and Marshall McLuhan's global village.
