Media – old or new, in the cloud or underground – constitutes the very condition in which our world takes shape. Media is reshaped continuously, marked for both the profound effects it produces and the acceleration it exhibits. It is the site in which we signal some of the most pressing issues we face in our ever-widening technologized world. Written by authors working at the forefront of media theory today, this book charts an original and compelling path across various media forms, bringing to light the wonderful yet persistently unsettling role that media plays, and will continue to play, in the making of our future. It not only establishes media as a serious and interdisciplinary concept, but also demonstrates how this concept can be developed beyond the current limited form and content dichotomy. This book was originally published as a special issue of Cultural Studies.
