A prominent presence in the news media is important for interest groups. This article investigates the development in the diversity of interest group media attention over time. The analysis draws on a dataset of 19,000 group appearances in the Danish news media in the period 1984–2003. It demonstrates how diversity has risen continually over time, leading to a media agenda less dominated by labour and business and more by public interest groups and sectional groups. This development is related to the increasing political importance of the news media and the decline in group integration in public decision-making processes. The article also shows how the development of group appearances is closely related to changes in media attention towards different policy areas.
