The competence area “media history” combines diverse basic and application-oriented research that pursue two key objectives: on the one hand, it looks at current communicative processes, which are characterised by references to history and the past in order to gain knowledge about the role of the media for memory processes of communities and societies. On the other hand, it addresses the historical communicative processes to provide knowledge concerning changes of media environments and their potential consequences from a long-term perspective for current debates. Both objectives are pursued in this area of competence by focussing on transmedia and transnational entanglements and their role in communitisation processes, which were produced through communication.
