The changes that have taken place in the artistic world in Portugal - since the 1980s - are materialize in manifestations that translate, in general terms, the democratization of culture and culturalization of society. These manifestations emerge and break with established logics that result in new forms of creation/ mediation/reception/conventions/canonizations. Our research focuses on these manifestations that namely take form of new do-it-yourself logics and work practices, in which artists/creators take over the role of producers/managers; and manifestations in which the position that gatekeepers and the processes to build reputations is central to promote these activities. Based on the analysis of content produced by a set of media (last ten years), it has been designed a territorial agenda of these artistic manifestations, which allows us to understand the incidence of these manifestations in the national territory and the emergence of new hegemonies in the Portuguese "cultural/artistic agenda" and the consequent processes of creation/mediation/reception/canonization.
