More than half of American homes now receive cablecasts, and 40 percent have video-cassette recorders. As these numbers grow, television screens will increasingly show the severe type of violence once reserved for the local movie theater. A more informative rating system is needed to accommodate this new onslaught. The current system is a weak precedent. The only qualification for selection to the Ratings Board of the Motion Picture Association of America is "parenthood." Its 12 anonymous members are paid from fees charged to movie producers and distributors who use the Board to rate their work. Ratings are made on the basis of what is seen on screen "and not what is imagined or thought," and advisories and restrictions are delimited by ages 13 and 17. The task of the Board is to estimate how other American parents would rate the suitability of the same film for their children. The current ratings process ignores decades of research in childhood development; children's intellectual and emotional growth are not delimited by age 0-13 years, 13-17 years, and over 17 years. Moreover, the negative effects of program content do not necessarily diminish with maturity. Still, there are measures that can be taken. Children can be taught "media literacy," so that they understand both the fictions and the effects of broadcast violence. Parents and teachers can be taught to select programs appropriate for the ages of their children and to look for the untoward effects of exposure to television violence. New technologies that would allow parents to shield their homes from violent shows should also be considered. Finally, the ratings system must be made wholly independent of those who profit by its neglect.
