USING TIME SERIES ANALYSIS TO MEASURE INTERMEDIA AGENDA-SETTING INFLUENCE IN TRADITIONAL MEDIA AND POLITICAL BLOG NETWORKS

Using time series analysis to gauge intermedia agenda setting in a sample of eighteen U.S. political blogs, two elite traditional news entities, and their eleven political newsroom blogs across three issues in 2007, this study reveals that traditional media were unable to set political blog agendas. Ideologically diverse political blog networks were also able to set traditional media's online news agenda, and, to a lesser extent, their newsroom blog agenda. Findings point to a dilution of traditional media's singular agenda-setting influence and to greater interdependence between traditional media and political blogs than suggested by hyperlink studies.
