This book challenges received views of communication models and opens up new paths of inquiry for communication research. By zooming in on the manifestations and purposes of modelling in ordinary discourses on communication as well as in theoretical expositions, the essays collected in this volume cast new light on the problems and prospects of models crafted for the benefit of communication inquiry. Complementing earlier studies of models of communication, the volume digs deep into fundamental epistemological and ontological questions concerning modelling in the communication disciplines; but it also presents several novel models that promise to be of practical use in empirical studies of media and communication.
