This book is a comprehensive introduction to media ethics and an exploration of how it must change to adapt to today's media revolution. Using an ethical framework for the new 'mixed media' ethics - taking in the global, interactive media produced by both citizens and professionals - Stephen J. A. Ward discusses the ethical issues which occur in both mainstream and non-mainstream media, from newspapers and broadcast to social media users and bloggers. He re-defines traditional conceptions of journalistic truth-seeking, objectivity and minimizing harm, and examines the responsible use of images in an image-saturated public sphere. He also draws the contours of a future media ethics for the 'new mainstream media' and puts forward cosmopolitan principles for a global media ethics. His book will be invaluable for all students of media and for others who are interested in media ethics.
