The age of digital media has given rise to a new social world. It is a world in which the transmission of information from the few to the many is steadily being supplanted by the multi-directional flow of facts, lies, and ideas. It is a world in which hundreds of millions of people are voluntarily depositing large amounts of personal details in publicly accessible databases. It is a world in which interpersonal relationships are increasingly being conducted in the virtual sphere. Above all, this is a world that seems to be veering off in unpredictable ways from the trends of the immediate past. This book is a probing examination of that world, and of the changes that it has ushered into our lives. In more than thirty essays by a wide range of scholars, this must-have second edition examines the impact of digital media in six areas---information, persuasion, community, gender and sexuality, surveillance and privacy, and cross-cultural communication---and offers an invaluable guide for students and scholars alike. With one exception, all essays are completely new or revised for this volume.
