Rethinking digital media and political change

<jats:p>The role of new digital media in politics has often been discussed for individual countries and technologies, or at a general level. So far, there are few studies which compare countries and treat new media in the context of the media system as a whole, including traditional and new digital media. The main contribution of this article is to compare two countries at the extremes of the political spectrum and with quite different media systems, the United States and Sweden. It synthesizes what is known to date about digital media in these two cases, including about the uses of Twitter, Facebook and other new media. The article discusses the shortcomings of existing analyses of political communication and of how digital media work in a way that is different from traditional or mass media. The argument is that new media expand input from people into the political systems only at the margins, where they can circumvent established agenda setting and gatekeeping mechanisms. The article develops a framework for understanding digital media which highlights how they extend and diversify the public sphere, even as this sphere is monitored and managed, and still faces the constraint of the limited attention devoted to political issues.</jats:p>
