The first book-long analysis of the 'mediatization of politics', this volume aims to understand the transformations of the relationship between media and politics in recent decades, and explores how growing media autonomy, journalistic framing, media populism and new media technologies affect democratic processes. As politics becomes increasingly mediatized, the role of the media becomes more important in political processes, overlaying and subsuming political logic. This affects not only the presentational aspects of politics but, it is feared, also policymaking processes. This may in turn have far-reaching implications as to how well democracy works. Against this background, Mediatization of Politics brings together state-of-the-art chapters written by leading scholars in the field of political communication. It synthesizes relevant concepts and arguments, identifies core components of the mediatization paradigm, and sets the agenda for subsequent work on the changing relationship between media and politics in general, and on the mediatization of politics in particular.
