Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Media regulators in many Western countries aim to ensure that consumers have access to diverse viewpoints in news coverage. A common argument is that this goal can be best achieved if there are enough independent sources in the market, implying that media policies should foster media competition. However, the effects of competition on viewpoint diversity are theoretically ambiguous, and empirical evidence is scarce. We address this gap by compiling a comprehensive dataset on the Swedish newspaper industry, covering multiple waves of mergers and acquisitions. To address endogeneity concerns, we exploit changes in multimarket contact between companies caused by out-of-market effects of ownership changes. Our results indicate that the consolidation of the industry substantially raised the average number of multimarket contacts, which induced newspaper companies to differentiate their slant more. As a consequence, the diversity of political viewpoints decreased both within companies and at the local market level, leading to reductions in readership. The findings suggest that increasing concentration of media ownership may have negative implications for democratic processes.
