We illustrate this research on circulation with the mod- el that Verón uses in the research on the exhibition of photographs (Verón; Levasseur, 1989): Figure 1 – Diagram on circulation – adaptation of the circulation model according to Verón PRODUCTION OPERATIONS SOCIAL DISCOURSES ↓ RECONNAISSANCE OPERATIONS Thematic exhibition as opposed to isolated work → Conceptual logics of the theme/ space → Disposition (mise en espace) subject to analysis Appropriation modes ← User models (motivations, cultural capital, relationship with knowledge, etc.). ← Source: Verón and Levasseur (1989, p. 31). This scheme is valid for research at the level of microanalyses, focused on understanding media events according to themes and agendas. It is interesting, however, that, for Verón, the exhibition, in the research to which the model refers, is understood as “media”. The media refers in the model more to
