The text is complemented by biographical notes and extensively cross-referenced, while web links supplement the entries. It is an indispensable guide for undergraduate students of media and communication studies, and also for those taking related subjects such as television studies, video production, communication design, visual communication, marketing communications, semiotics, and cultural studies.
