The Impact of State Television on Voter Turnout

  • Rune J. Sørensen


In an influential study, Matthew Gentzkow found that the introduction of TV in the United States caused a major drop in voter turnout. In contrast, the current analysis shows that public broadcasting TV can increase political participation. Detailed data on the rollout of television in Norway in the 1960s and 1970s are combined with municipality-level data on voter turnout over a period of four decades. The date of access to TV signals was mostly a side effect of geography, a feature that is used to identify causal effects. Additional analyses exploit individual-level panel data from three successive election studies. The new TV medium instantly became a major source of political information. It triggered political interest and caused a modest, but statistically significant, increase in voter turnout.
