Advertising Age obtained ad revenue and/or page counts from PIB/TNS Media Intelligence/CMR, VNU’s Perq/HCI and Ad Age’s quarterly Consumer Linage Reports. Ad revenue calculations don’t take into account multiple insertions, special discounts and off-the-rate-card deals. Gross ad revenue for non-monitored magazines is determined by multiplying its one-time black & white rate by total ad pages.
Circulation revenue was calculated by multiplying paid subscribers by subscription price, and newsstand sales by frequency and the single-copy price. Sources for circulation: Audit Bureau of Circulations, BPA International and directories on consumer, business and health publications from Standard Rate & Data Service. Circulation is confined to North America.
Though subscription and single-copy prices may change in the year, only end-of-year prices are applied to subscriber and newsstand counts. Association magazines count only the portion of membership dues dedicated to the publication. Data are confirmed by publishers, who are allowed to make adjustments as long as those adjustments meet AA criteria.
