Foremost scholars explore new directions in communication research in the light of social, economic, and technological changes in recent years. They analyze differing perspectives historically, problems and opportunities in terms of information flows and filters, and new public policy and social issues and challenges. They raise major questions about future needs and trends. This interdisciplinary study delves into a number of basic concerns, such as how public agendas are formed, how shifting groups in society interpret messages differently, and how technology has changed profoundly the ways in which we communicate in the world today. This overview of the state of communication research is designed for scholars, professionals, and for student use in research methods courses.
