抗议活动现在是西方民主国家政治的核心，但公民主要通过媒体的描述了解它。然而，媒体只报道了公众抗议活动的一小部分，这增加了选择偏见的可能性。我们通过比较1982年和1991年在华盛顿，华盛顿特区的示威游行的警方记录与《纽约时报》、《华盛顿邮报》和三个国家电视网对事件的媒体报道来研究这个问题。我们模型的示威形式，上下文和目的的媒体报道的可能性的后果。示威活动的估计规模及其对当前媒体关注周期的重要性是其报道的最强预测因素。其他分析支持我们的说法，即媒体对一个问题的高度关注增加了与该问题有关的抗议活动被报道的可能性。将1982年与1991年进行比较表明，电视对抗议活动的报道越来越受到媒体关注周期的影响。
Protest is now central to politics in Western democracies, but it is known to citizens mainly through portrayals in the media. Yet the media cover only a small fraction of public protests, raising the possibility of selection bias. We study this problem by comparing police records of demonstrations in Washington, D.C. in 1982 and 1991 with media coverage of the events in The New York Times, The Washington Post, and on three national television networks. We model the consequences of demonstration form, context, and purpose on the likelihood of media coverage. The estimated size of a demonstration and its importance to the current media issue attention cycle are the strongest predictors of its coverage. Additional analyses support our claim that heightened media attention to an issue increases the likelihood that protests related to that issue will be covered. Comparing 1982 to 1991 suggests that television coverage of protests is increasingly subject to the impact of media issue attention cycles.
