This book is a contribution to answering the question, ‘What is new about “new media”?’ It also offers ways of thinking about that question, ways of seeking answers. Here, at the outset, we ask two prior questions. First, ‘What are media anyway?’. When you place the prefix ‘new’ in front of something it is a good idea to know what you are talking about and ‘media’ has long been a slippery term (we will also have a lot to say about that in various parts of the book). Second, what, at face value and before we even begin to interrogate them, do we include as ‘new media’?
