The text reports on research carried out in 2018, the objective of which was to identify the contributions and limits of digital uses in the mediation of contemporary art. An empirical study conducted on two sites, the Musée d’art contemporain de Montréal (MAC) and the PHI Foundation for Contemporary Art (FP)1, shows that technologies contribute to the project of cultural democratization: they accentuate the visibility of institutions and come in a variety of media, reaching out to different types of people and needs. However, reluctance to use digital tools exists because of the amount of resources they mobilize while their sustainability is not guaranteed.
