Research scrutinizing political talk online has been developed largely against the backdrop of deliberative discursive norms and considered political talk without a systematic analysis of surrounding mass-mediated discourses. By contrast, this study operationalizes counterpublic theory as an alternative theoretical perspective and analyzes comments on news websites as a reaction to hegemonic mainstream public spheres. It juxtaposes a qualitative framing analysis of all articles about a new anti-Euro party in devotedly pro-European Germany published on 9 news websites in the week following the 2013 elections (n = 22) with a content analysis of all comments posted below these articles (n = 3,154). It finds counterpublic spheres differently shaped in comment sections of right- and left-leaning, and tabloid and nontabloid, outlets. Consequences for democracy are discussed.
