A necessary step in an effective public education campaign is obtaining sufficient broadcast time to reach substantial numbers of a target audience. By this criterion, the 1982 Alcohol Abuse Prevention Campaign was very successful. Between February and December 1982, 17,409 alcohol-related public service announcements (PSAs) were broadcast in 75 major media markets around the country. Campaign messages reached target audiences with sufficient frequency to have had likely effects on attitudes and behavior. Key elements in the success of the effort were producing high quality broadcast materials, providing technical assistance to aid state and local groups in the message dissemination process, and providing for state and local control over the timing and release of materials.
有效的公共教育活动中的一个必要步骤是获得足够的广播时间，以覆盖大量目标受众。按照这一标准，1982年预防酒精滥用运动非常成功。在1982年2月至12月期间，全国75个主要媒体市场共播出了17409条与酒精相关的公益广告。运动信息以足够的频率传达到目标受众，可能对态度和行为产生了影响。这项工作成功的关键因素包括制作高质量的广播材料，在信息传播过程中为州和地方团体提供技术援助，以及让州和地方控制材料的投放时间和发布。
