Réseaux. The French journal of communication - Année 1997 - Volume 5 - Numéro 1 - Pages 27-48Summary: This paper, based on the Irish example, reports on the role of a news agency, Agence France Presse, in the construction of an event. The author shows how the agency, under constraints of time and thematic production, selects and classifies subjects. It thus reduces situations to events by highlighting the themes likely to have news value. In the final instance it is, however, the agency's clients, the media, which re-cast the news in relation to the context in which it is to be received. 22 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
