This article focuses on the distribution of enunciative heterogeneities in a specific discourse genre: press texts that give information on the controversies and polemics in present societies. First, a description is provided showing how the intratextual meetings between antagonistic utterances are represented, named and caracterised by the journalist. The framing of the speech thus represented is then anaysed, especially concerning the role of metalinguistic categorization (for example, the words débat or argument with their syntactico-semantic cotexts) within the discursive progression of the text, and also the phenomenous or reprise (anaphoric and thematic reference) and reformulation. The last question is how to work anew on concepts borrowed from Bakhtin/Volochinov so as to attempt to explain the development of this type of texts in the construction of events, along with the evolution of the media and, more widely, the history and the memory of societies.
