Book excerpt: The ‘Milestones’ essays in Mass Communication and Society are reflective and analytical articles by the most notable scholars in the field. These classic essays address 21st century issues from the pioneers of media and communication studies, including Elihu Katz on new media and social movements, George Gerbner on cultivation analysis, and Dietram Scheufele on political communication. As technologies evolve and mass communication becomes mobilized and democratized - more individual and also more social - these landmark scholars provide ideas about how established theories may be applied in new ways, and how future research can expand our understanding of mass communication as its reach and effects grow ever larger. This book will be essential reading for both students and researchers of Mass Communications Research.
