Editing Agenda-setting theory (section)

=== Development of agenda-setting theory ===

By comparing and developing the salience of issues in news content with the public's perceptions of the most important election issue, McCombs and [[Donald Lewis Shaw|Shaw]] were able to determine the degree to which the media determines [[public opinion]]. Since the 1968 "Chapel Hill" study, published in a 1972 edition of ''[[Public Opinion Quarterly]]'', more than 400 studies have been published on the agenda-setting function of the [[mass media]], and the theory continues to be regarded as relevant.
