What do we know about the relationship between public media and private media and their respective impacts?

The Reuters Institute for the Study of Journalism (RISJ) has published a new report commissioned by the Danish Ministry of Culture.

The report reviewed the status of public service media and private media by examining over a thousand academic and stakeholders studies.  The research covered three main aspects: their political impact, social impact, and market impact.

The research indicates that there is strong evidence that public service media have a positive political impact. However, there is little research on the social and market impacts.

As RISJ says, “what we do not know about the impact of public service media, especially in a digital environment, is at least as striking as what we do know.”
