The emergence of what are called new media' & social media' is one of the most discussed topics in contemporary societies Because media & public communication are mostly analyzed within particular theoretical frameworks & within specific disciplinary fields polarized views have been created with cyberoptimists & celebrants on one side & cyberpessimists & skeptics on the other Thus we lack an understanding of the interdependencies & convergence between disciplines & practices The second edition of this book expertly synthesizes competing theories & disciplinary viewpoints & examines the latest data including international research from fast-growing markets such as China to provide a comprehensive holistic view of the twenty-first century media (r)evolution Dr Macnamara argues that the key changes are located in practices rather than technologies & that public communication practices are emergent in highly significant ways Engaging & accessible this book is essential reading for scholars & professionals in media & communication & an invaluable text for courses in media studies journalism advertising public relations & organisational & political communication
