5. Discussion
The results detailed above seem to indicate that PR emerged as a process of adaptation of communicative behaviour on the part of societal actors or organisations. This was triggered by the performance ofthe journalistic system, perceived by them as limited. At the same time we see an increasing social pressure on organisations to legitimate themselves. What is interesting is that this process of adaptation is theorised in the mediated social communication (MSC) approach (Fürst, Schönhagen & Bosshart, 2015). Wagner (1980) conceptualises the development of communication in society, on the basis of work by Riepl (1913) and Knies (1857/1996; see also Hardt, 2001, pp. 67–83) and others, as a succession of processes of rationalisation. Thus, mass communication constitutes the temporary conclusion of these processes and, in modern complex societies, enables comprehensive social communicationthroughintermediationofmassmedia andjournalism. The latterpublishes the statements of various societal groups and actors in a concentrated and compact form. This makes the statements and views of the various stakeholders and organisations observable for the entire society, thereby enabling further communication. This constant intermediation of communication is performed autonomously, i.e. not serving particular interests but the public discourse as a whole (Schönhagen, 2004, pp. 117–130; Wagner, 1980).
