In the area of science journalism studies there are only a few studies that are catholic in focus, most of them analyse the press, just three are catholic and longitudinal in scope and only one is comparative additionally. The research focussed almost exclusively on the classification of content areas, for instance the allotment of biology or medicine or social sciences within the sample. The approaches are mainly atheoretical, if not, they prefer theories from the disciplines they derive from: sociology mainly, psychology, linguistics. The perspective of all studies - especially the international ones - is still almost completely science centred in the sense that they are not specifically interested in the structures of media systems which enable and determine the extent and quota of the science content being produced. In this area we highly lack knowledge.

Our approach is catholic in focus, that means, we selected every single science programme available in all sampled 13 European Countries on channels, which together reach a market share of at least 85 percent.

Our approach is media centred, that means, our concept is led by the idea, that mainly differences in media structures explain differences in the way, how science is perceived by specialised units within TV and Radio.

Our approach focus on differences of the perception of science by journalism, which affects organisational matters, that means that we distinguish programmes with regard to their relatedness to science and their up-to-dateness.
