By going back to the critical moment of the cybernetisation of the museum and of the exhibition, this essay aims to put forward a thesis considering exhibition as medium. It elaborates on the notion of medium by contrasting it with Canguilhem’s notion of milieu, in order to redefine it, in a non-substantialist way, as modulation in light of Simondon’s and Deleuze’s works. It proposes a genealogy of the exhibition as medium and describes a critical historical trajectory shaped by institutional and (...) informational infrastructures. (shrink)
