This is not a compendium of TV trivia but rather a serious work intended "to be the reference work of first record, the beginning point for anyone interested in exploring and understanding the significance of television in our time." Under the auspices of the Museum of Broadcast Communications in Chicago, some 300 contributors have addressed a variety of issues and topics. Entries range in length from one to several pages and include suggestions for further reading. Crisp black-and-white photographs, such as studio publicity stills and headshots of individual personalities, are sprinkled throughout the double-column text. Although there are entries on individual television programs complete with cast lists, these are offered only for programs considered to be of particular significance?typical of a certain program genre, controversial because of subject matter, the first of its kind, etc. More commonly, the essays cover broader topics (e.g., the history of a network or organization and subjects like censorship of tabloid television). Notable individuals, from performers to producers to inventors, are also profiled. The focus may be on television in English-speaking countries, but the scope has been widened to include articles surveying the medium in more than a few other countries. From "Absolutely Fabulous" to "Vladimir Zworykin," this is a gold mine of information for those toiling in the fields of communications, popular culture, and related subjects.
