Since the early nineties, an ever increasing number of artworks have been created on the basic of preexisting works; more and more artists interpret, reproduce, re-exhibit, or use works made by others or available cultural products. This art of postproduction seems to respond to the proliferating chaos of global culture in the information age, which is characterized by an increase in the supply of works and the art world's annexation of forms ignored or disdained until now.
