This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book explores theoretical grounds of the “communicative city”. Gumpert and Drucker reconsider their formative definition and raise a series of questions and provocations concerning future research directions and approaches. The book focuses on the growing implication of digital media in contemporary practices of placemaking. Sun Wei explores the entanglement of embodiment and mediation in her account of the redevelopment of Sinan Mansions, while Christiane Brosius reflects on the complex urban ecology of Delhi through the work of two contemporary artists. The book focuses specifically on the communicative possibilities of a distinctive aspect of the contemporary media city, namely large video screens situated in urban public spaces. It also focuses more directly on the different ways that digital media platforms have become a new infrastructure shaping the contemporary communicative city.
