Crossmedia and transmedia are keywords of increasing importance for media professionals and scholars alike. Although these phenomena are older than sometimes argued, the affordances of digital networked media have radically enriched the nature of «crossmedia strategies» of media industries. As such crossmedia is an emergent practice that arises as one of the core sources of complexity and innovation for late modern cultures. This edited volume includes chapters by authors from three continents who approach the phenomenon from different disciplinary angles: semiotics, cultural studies, media economics, political economy, innovation studies. The common interest lies in the dynamics that lead to experiments with crossmedia and in how our cultures are innovated through such practices.
