关于媒体与民意的理论大部分提出于 1 93 0到 1 980年之间 ,这是一个仅仅拥有传统信息选择方式的时代。麦库姆斯和肖 (1 972 )最初提出议程设置理论时 ,用北卡罗莱纳州的教堂山 (ChapelHill)社区作为研究对象 ,而现在那里的媒介使用情况也已经发生了巨变。当我们迎来议程设置理论提出 3 0周年的时候 ,教堂山的受众现在面临的信息选择令人惊叹。在 2 0世纪 90年代 ,肖提出 ,美国的大众媒介已经经历了“兴和衰”(riseandfall)。肖认为 ,大众媒体时代结束于 2 0世纪 80年代。议程设置研究是否能像之前的 3 0年那样 ,继续开展下去 ?当受众使用着上百个信息来源时 ,议程设置和民意研究会产生何种变化 ?这是本文将要回答的问题 Much of the theory of media and popular opinion was put forward between 1993 and 1980 and was an era of merely having the traditional way of choosing information. When McCoums and Shaw (1972) initially proposed agenda-setting theory, they used the Chapel Hill community in North Carolina as their subject, and the media usage has changed dramatically. When we celebrate the 30th anniversary of the agenda-setting theory, the audiences in Chapel Hill are now facing astonishing choice of information. In the 1990s, Shaw proposed that the mass media in the United States have undergone “rise and fall”. Shaw believes that the mass media era ended in the 1980s. Can agenda-setting research continue as it did in the previous 30 years and what changes will be made to agenda setting and opinion polls as audiences use hundreds of sources of information? This is the question to be answered in this article
