This article is the first review of research undertaken since the early 1990s on French journalism. It shows, first, how this space is structured around opposition between a "general-interest" pole and a "specialized" pole. It then compares several specialized sub-fields in terms of a number of variables: position in the journalistic field, varied weight of different media in the production of specialized news, degrees and forms of competition and collaboration, and so on. Finally, the author compares the different specialized sub-fields of journalism and the corresponding social spheres by studying the degree of interrelatedness between their respective economies, the degree of political control of activities, the degree to which the different actors impose their problematiques and principles of hierarchy, and the social characteristics of journalists and their interlocutors.
