In recent years, the study of policy advisory systems has been advanced conceptually and analytically through studies of externalisation and politicisation. Still, the understanding of institutional variation in how organisations supply policy advice remains limited. The contribution adds to recent research on think and the study of policy advice by arguing for a focus on the dissemination of policy advice by asking how the dissemination activities of think tanks vary across different policy advisory systems and what this implies for the study of policy advice. This question is explored in a quantitative design which compares publications, events and newspaper mentionings of samples of think tanks from a coordinated (Germany), liberal (UK) and mixed (Denmark) system in 2012. The analysis indicates that think tanks in the UK have the highest level of dissemination on all three activities when controlled for the number of full-time staff. The study indicates that factors beyond the policy process such as developments of funding and media environments should be analysed further as they are likely to be important for how and where think tank disseminate their policy advice.
