Abstract
This article presents the concept of tactical media, its emergence in forms of activism associated with the media, as well as its roots in punk ethics and Michel de Certeau's thinking, with the aim of identifying its expressions in the visual arts, and particularly in contemporary Brazilian art. We believe that this concept, still not so much explored by art researchers, can activate new perspectives about artworks that produces subversive and poetic uses of mass media, diverting them from their original purposes.
