The question of the location of media became virulent with the ubiquitous spread of computers. The digital medium is considered universal because its openness to purpose and indifference to multimedia uses put familiar terms like machine, medium, and technology into question. McLuhan's prematurely popularized thesis that media transmit former media gains new clarity under the digital paradigm: The mediality of media lies in their metaphorical nature, meaning in the interstitial space of transmissions that evade or shift teleological meanings. Beyond the anthropological and instrumental discourse on media, the contributions gathered in this volume attempt to explore the idiosyncratic horizon of media theory.
