The book considers the nature and consequences of a number of important new digital technologies and practices, including human-machine communication, software, mobile marketing, online reviews, big data, 3D printing and a wide range of other digital innovations. Many of these technological developments were completely unanticipated and as such the transformation is still unfolding. Therefore, whilst consumers have largely embraced and actively co-create many of these new innovations.
