The power of the press to set political agendas is dependent upon a consensus among journalists and the media on the topics deemed newsworthy. By analyzing the content of four television newscasts and four national newspapers between 2000 and 2005, this article empirically measures the level of diversity of the Chilean news media agenda according to the frequency with which specific topics appear in the news. The results reveal a very high level of uniformity between news agendas, which is consistent over time despite the differences in format, editorial line, and targeted audience of each news outlet. This article suggests some of the causes and consequences of this homogeneity for the quality of the public debate and the political system.
