This overview of studies from 1970 to 1975 sponsored by the American Broadcasting Company summarizes the research efforts of five years. In relatively concise but more than outline form, the studies, the findings to date, and directions pursued, and their implications for the broadcasting industry are presented. The 11 studies described dealt with violence or aggression effects from television viewing on children, adolescents, and young adults who were emotionally troubled or otherwise potentially vulnerable to televised messages. Implications for the broadcasting industry in light of the findings of the studies are presented. (HB)
