Agenda-setting theory

Agenda setting describes the "ability (of the news media) to influence the importance placed on the topics of the public agenda". The theory suggests that the media has the ability to shape public opinion by determining what issues are given the most attention, and has been widely studied and applied to various forms of media. The study of agenda-setting describes the way media attempts to influence viewers, and establish a hierarchy of news prevalence. Nations judged to be endowed with more political power receive higher media exposure. The agenda-setting by media is driven by the media's bias on things such as politics, economy and culture, etc. The evolution of agenda-setting and laissez-faire components of communication research encouraged a fast pace growth and expansion of these perspectives. Agenda-setting has phases that need to be in a specific order in order for it to succeed. The theory was first introduced by Walter Lippmann in the 1920s and further developed by Bernard Cohen in the 1960s. The theory was formally developed by Maxwell McCombs and Donald Shaw in a study on the 1968 presidential election, which found a correlation between the issues covered by the media and the issues perceived as important by the public. Agenda-setting theory was formally developed by Dr. Maxwell McCombs and Dr. Donald Lewis Shaw in a study on the 1968 presidential election deemed "the Chapel Hill study". McCombs and Shaw demonstrated a strong correlation between one hundred Chapel Hill residents' thought on what was the most important election issue and what the local news media reported was the most important issue. By comparing the salience of issues in news content with the public's perceptions, McCombs and Shaw determines the degree to which the media sways public. The theory also suggests that media has a great influence to their audience by instilling what they should think about, instead of what they actually think. That is, if a news item is covered frequently and prominently, the audience will regard the issue as more important.
