This book shows how disinformation spread by partisan organizations and media platforms undermines institutional legitimacy on which authoritative information depends.

This handbook is one of the first comprehensive research and teaching tools for the developing area of global media ethics. The advent of new media that is global in reach and impact has created the need for a journalism ethics that is global in principles and aims. For many scholars, teachers and journalists, the existing journalism ethics, e.g. existing codes of ethics, is too parochial and national. It fails to provide adequate normative guidance for a media that is digital, global and practiced by professional and citizen. A global media ethics is being constructed to define what responsible public journalism means for a new global media era. Currently, scholars write texts and codes for global media, teach global media ethics, analyse how global issues should be covered, and gather together at conferences, round tables and meetings. However, the field lacks an authoritative handbook that presents the views of leading thinkers on the most important issues for global media ethics. This handbook is a milestone in the field, and a major contribution to media ethics.
