Advertising revenue in most cases is obtained from monitoring services, including Publishers Information Bureau, Competitive Media Reporting, Perq Research Corp., Space Analysis Systems and the quarterly Consumer Linage Reports in Advertising Age.
GROSS REVENUE DEVELOPED
When advertising is largely local, retail or combination, AA works with the publisher to develop a gross revenue total for advertising.
Circulation revenue is the sum of revenue generated by subscription and newsstand sales.
The various components in determining gross revenue (paid subscribers, subscription cost, single-copy sales and newsstand price and frequency) come from various sources: Audit Bureau of Circulations, BPA International and directories on consumer, business and health publications from Standard Rate & Data Service. Data are confined to North America.
In a few cases where current-year circulation is not available, magazines either provide it directly or AA estimates circulation by applying a growth figure tied to the magazine's segment.
Magazines are sorted by their current SRDS primary classification, except for computer/Internet/electronic games, which AA has grouped into a single category. Classifications for many publications are fluid; many straddle two categories. The classifications of a magazine appears with its listing in the index.
