A History of Mass Communication traces the common themes in the long and complex history of mass communication. It shows how the means of communicating grew out of their eras, how they developed, how they influenced the societies of those eras, and how they have continued to exert their influence upon subsequent generations. The book is divided into six periods which are identified as 'Information Revolutions' writing, printing, mass media, entertainment, the 'toolshed' (which we call 'home' now), and the Information Highway. --From publisher's description.
