Case study research is well established in communication studies and media policy analysis. In the literature a distinction is often made between qualitative analysis on the basis of a single or a small number of in-depth case studies versus a cross-case analysis on the basis of a large amount of quantitative data. Quick-scan analysis allows for cross-case analysis of a more extensive amount of smaller qualitative case studies (20-40 cases). It describes multiple small case studies on the basis of a limited set of variables. By mapping the variables and its indicators in a single matrix the analysis of similarities, differences and variances over the cases becomes possible.
