The aim of this article is to contribute to the discussion surrounding mediatization by presenting some arguments on how we could include questions of media specificity in an appropriate way. The core argument is that we have to do this by integrating `media specificity' into a theory of communicative practice or action. In doing so, we can grasp media in their institutional and technological sense as `molding force' of communicative action and research them empirically as part of mediatization processes.
