This book presents material from a symposium on television violence that was organized by the Canadian Radio-Television Commission. Part 1, "The Public Issue," discusses the social effects of mass media and violence as a dramatic convention. Part 2, "The Social Effects of Television Violence," provides experiments, research, and patterns in research. Part 3, "The Industry Perspective," discusses the quality and economics of Canadian television production. Part 4, "Control and Improvement," presents the legal and social implications of control mechanisms as they relate to mass media and summarizes the symposium. Lists of the background papers presented at the symposium, their bibliographies, and the names of symposium participants are appended. Some of the papers are printed in both French and English. (RL)
