This Introduction presents the context for the book’s argument of the post-screen, namely, an argument for a state of critical attention to the delimitations of screen media and the ensuing problematizations of relations between image and object; an intensifying evolution of the virtual and its role in defining media consumers and their realities; and an era of screen media marked by the disappearances of boundaries of differentiation between subject and object; and a point in media history. The central query of the post-screen lies in the growing imperceptibility and instability of screen boundaries. Where these thresholds begin to disappear is also where the need arises to re-question the definitional states of the actual and the virtual, and the renewed contestations for dominance between them.
