| Abstract: | Although the theory of agenda-setting is a pillar of political communication research, understanding the dynamics of public attention remains an important challenge as the communication system becomes increasingly fragmented. The development of ideologically oriented niche media and the ability of the mainstream media to carefully track the interests of their audience suggest that both public interest and niche media attention to an issue could affect the mainstream media’s agenda itself. We develop and test the theory of agenda-uptake to isolate when mainstream media influences both public and niche media attention to issues and when public interest and niche media attention influence the mainstream media to cover an issue. Analyzing mainstream and niche media coverage along with Google Trends individual search data for 4 issues in 2008, we provide evidence that the dynamics of agenda-uptake are crucial to understanding the character and content of the information environment in the 21st century. |
