Telling a Different Story: A Longitudinal Investigation of News Diversity in Four Countries.

News diversity is an important concern of journalism scholars, as its presence or absence can have a profound effect on democratic debate and the information available to citizens. Many have speculated that news diversity decreases over time, due to changing economic circumstances. This expectation especially applies to newspapers. Using nearly two decades of newspaper data from four European countries (Denmark, The Netherlands, Norway, UK), we do not find this expected decrease in news diversity. When conducting pairwise, automated comparisons between articles published on the same day in the same country, we rather find a modest over time increase in diversity between newspapers. This result suggests that newspapers differentiate rather than converge in the content they offer, shedding a more positive light on the evolution of the press in our current high-choice media environments.
