This book offers a wealth of original empirical data on how online media shape EU politics. The authors highlight myths and facts about the nature of audience-driven online media content and show how public demands for legitimacy are at the heart of the politicization of European integration. What EU citizens most intensely debate online are fundamental questions of what European institutions stand for and how they can be held accountable. Drawing on innovative and rigorous analysis of online media ownership, journalistic content, and readers’ input, the authors piece together the convergence toward Euroskepticism across EU member states.
