Reviews the findings of communication research on the effects of televison on violent behaviour, and the history of the use of this information in policy-making. To what political use has violence research been put? What impact has it had on politics? The interactions of federal communication policy, the broadcasting industry, public or citizens' interest groups, and the communication research community are described. The rise of TV violence as an issue is documented, in the context of the rise of social science as a policy-making resource. Rowland uses hearings, records, and reports of congressional committees and national commissions to reveal the patterns of argument and shared assumptions, and the structure of interactions among groups and institutions. These records are also part of our rituals of social self-examination. Rowland's approach rises out of the tradition of critical cultural studies, with its emphasis on history and symbolic analysis. His book, finally, is about the symbolic uses to which communication research -- indeed, social science -- is put to alleviate contemporary tensions and unease.
