This article analyzes interactivity in online journalism as a powerful myth with which journalists have to deal in their daily work. A constructivist approach to media innovation is used to explore the historical origins of the myth that predicted interactivity would change journalism and to confront it with the actual practices of online media projects through published empirical research and four case studies selected from an average European regional market. The analysis of the cases is based on ethnography of online newsrooms working routines and in-depth interviews with reporters, editors and web developers. The actual role of the myth of interactivity in shaping the development of these four online news projects is discussed taking into account the material and organizational context of the newsrooms. Findings suggest that the professional culture of traditional journalism has a strong inertia in the online newsrooms that prevents them from developing most of the ideals of interactivity, as they do not fit in the standardized news production routines.
