Abstract
This article develops a theoretical classification of functions of different Internet applications and plattforms in right-wing populism. Its aim is to understand how the Internet is seen and used by populists and how it contributes to populism. Online communication by both populist leaders or organizations and non-organized actors is discussed. Main functions include the representation of the relationship between leaders and ‘the people,’ justifying the exclusion of outgroups, the conceptual elaboration of the right-wing populist ideology, developing a right-wing populist lifestyle and identity, and circumventing the traditional media.
