This class focuses on the complex relationship between the institutions of the art world and the artistic practices linked to new media, from the transgressive proposals of net art to the progressive though unfinished integration of works of digital art in the collections of some museums. Examining both the problems involved in the conservation and dissemination of unstable art and the pre-eminence of temporary exhibitions in front of permanent collections, we will see how in their interaction with new technologies both artistic practices and museums themselves are transformed.
