Selective media exposure and increasing knowledge gaps in Swiss referendum campaigns

This study aims to contribute to the discussion on how the growing opportunities for media choice influence gaps in political knowledge among those motivated to consume news versus those who are not. With more television channels available, it becomes easier to choose content matching personal interests. While several studies have analyzed trends in news consumption and motivations among different citizen groups, there are still very few studies that actually link these developments longitudinally to patterns of knowledge gaps. Using survey data from Swiss referendums held 1993–1999, we find that (1) gaps in political knowledge because of political interest have increased over time, and (2) political interest has become a stronger predictor of informational TV use
