1. Introduction

All media are new when they appear on the horizon and old by the time another, newer, medium arises. Indeed, the depiction of a medium as new connotes that something in this medium is different that sets it apart from existing media. In this book we will elaborate on the unique features that define new media: their interactivity, their potential to be mobile, their potential to access and deliver infinite amounts of data, and the potential they give users to express themselves in a variety of ways utilizing written words, sounds, and still and moving images and be heard by many others simultaneously. We will then explain why these defining elements of new media carry the opportunity to shift current communication policies from their utilitarian-based approach to a justice-based one.
