broadcasting and describe the underlying principles, standards, and equipment for broadcast facilities, in terms a layperson can understand. The third edition has been completely revised to reflect the increasing use of digital techniques in all aspects of television and radio broadcasting. It has been reorganized and some obsolete material removed, while also updating the basic information on traditional analog technologies. New chapters have been added to provide an overview of first principles and current standards in the broadcast industry. We concentrate on over-the-air broadcasting from U.S. radio and television stations, but also mention some of the other methods of program delivery to the home and outline some of the different standards and technologies used in other countries."

access to information not available through the mass media. It will also examine the ‘information for action’ orientation of much alternative media, which places it in opposition to the mass media’s ‘information for consumption’. Chapter 2 puts the emergence and persistence of alternative and activist media in context, calling into question media analysis that looks strictly at mass media, and posing the possibility and reality of counterhegemonic actions and actors. It includes an overview of key theorists as regards alternative media and media activism. Chapter 3 looks specifically at media participation and consumption by marginalised audiences. The following five chapters look at alternative and activist media formats and rationales in the realms of radio, video, film, print, and digital media, concentrating on real-world practices and projects. In Chapter 9, the border between alternative and activist media and the mass media is probed, revealing areas of contention, reflection, and recuperation. Chapter 10 concludes this exploration with a look at the future, based on an examination of current trends and technologies." (Preface, page ix)
