This editorial delivers an introduction to the thematic Media and Communication issue on “The Turn to Affect and Emotion in Media Studies”. The social and cultural formation of affect and emotion has been of central interest to social science-based emotion research as well as to affect studies, which are mainly grounded in cultural studies. Media and communication scholars, in turn, have especially focused on how emotion and affect are produced by media, the way they are communicated through media, and the forms of emotion audiences develop during the use of media. Distinguishing theoretical lines of emotion theory in social sciences and diverse traditions of affect theory, we reflect on the need to engage more deeply with affect and emotion as driving forces in contemporary media and society. This thematic issue aims to add to ongoing affect studies research and to existing emotion research within media studies. A special emphasis will be placed on exploring structures of difference and power produced in and by media in relation to affect and emotion.
