Editorials define at a given time how media construct their socio-cultural environment and where they position themselves in it. In this sense, they are snapshots of media socio-cultural identities whose study is crucial for the understanding of media actions and interactions on the political stage. This book contributes to the study of media roles in politics with a methodological “discursive communication identity framework” and its application to a corpus of editorials. This allows for the definition of editorials as a genre, and it reveals that, thanks to a very adroit interweaving of their socio-cultural identities, news media can play a much more active role on the political stage than studies on framing and agenda setting have hitherto shown. The place of media in political communication models might therefore need to be reviewed.
