This reference book profiles corporate magazines, those sponsored by and produced for a single business firm. Some of these periodicals are internal, aimed at the company's own employees and retirees. Others are mainly external and are directed at a broader audience of stockholders, customers, and readers outside the corporation's immediate family. Still others have a dual role, and target both internal and external audiences. Some of these magazines are quite old--the oldest profiled here dates from 1865. Some have enormous circulations, the largest having reached nearly 12 million bimonthly, though they rarely produce circulation revenue. This is the first book to fully consider this genre of magazine publishing. Journalism and communication scholars examine a representative sample of 52 of these magazines in individual descriptive essays, each with appended publishing history and information sources. Bibliographic information is necessarily limited. Entries are arranged alphabetically and each entry appears in additional appendixes which classify the profiled magazine by founding date and geographic location. An end-of-volume appendix provides brief data on 232 additional magazines.
