The Euro crisis has led to an unprecedented Europeanization and politicization of public spheres across the continent. In this volume, leading scholars make two claims. First, they suggest that transnational crossborder communication in Europe has been encouraged through the gradual Europeanization of national as well as issue-specific public spheres. Second, the politicization of European affairs - at the European Union (EU) level and in the domestic politics of member states - is inevitable and here to stay. Europeanized public spheres, whether elite media, mass media, or social media such as the internet, provide the arenas in which the politicization of European and EU issues takes place. European Public Spheres explores the history of these developments, the nature of politicization in the public spheres as well as its likely consequences, and the normative implications for European public life.
