Abstract : We are interested in the organisational changes in identity, brought about by the juxtaposition of paper and electronic media in the domain of daily newspapers. We define these changes through a specific case: placing the daily newspaper Le Monde on the Internet as Web pages. Our concern is how changes in identity, related to placing a daily newspaper on-line, are understood by a «communicational reading». We explore the on-line newspaper industry using «l'approche communicationnelle» (Alex Mucchielli, 1997, 1998, 2000). This approach pays particular attention to the communication processes which define the on-line newspaper industry. Our objective is to research how the nature of journalism arises, sets itself up and evolves with the help of information and communication technologies.
