Purpose - To examine the evolution of the online newspaper genre in Scandinavia. To provide an understanding of the institutional context in which online newspapers initially were produced and modified over time. Design/methodology/approach - A longitudinal study of three different types of newspapers in three Scandinavian countries. The study is based on interviews with newspaper representatives conducted during recurring visits in 1996, 1999 and 2002, and web page analysis of their online newspapers. Findings - The study illustrates how online newspapers have established a number of communicative practices significant for recognizing them as a distinct digital genre, and it outlines a set of institutional factors shaping the ongoing change of these newspapers. In addition, the study demonstrates the emergence of sequential interdependencies between online and printed news. Originality/value - The focus on Scandinavian newspapers in this paper complements studies conducted in other parts of the world regarding online newspaper genre evolution.
