Science communication has been defined as encompassing “all forms of communication by and about the sciences, within science (professional audience) as well as in the [broader] public sphere (general audience)”. This broad understanding of science communication includes all kinds of communication focusing on scientific work or scientific results, within science or to non-scientists, in one-directional or dialogical form. It also includes communication about the natural sciences, the arts or the humanities, and it has considerable overlaps with research fields such as health communication and risk communication. Content analysis, especially of media content, is a common method in the research field and this article provides an overview of this research.
