Grusin's latest book, "Premediation: Affect and Mediality After 9/11" (2010), develops and extends the theory of premediation. It argues that at least since the new millennium, networked global media seek to ensure that the future is already pre-mediated before it emerges into the present. The book also explores how the phenomenon of premediation produces and maintains a low level of anxiety in relation both to the global war on terror and to such other post-9/11 threats like climate change, cybersecurity, or financial crises. Grusin posits that in our current era of mobile socially networked media, the function of print, televisual, and networked media is to produce and maintain both individual and collective affects of anticipation, which keep the digital citizens of the 21st-century oriented towards the premediated future.
