While some newspapers globally are agonising over the killing fields of the internet and whether paywalls can solve the problem of fiscal death by click, others have joined magazines in a whole new approach to the digital dilemma: add online readers into your total circulation base and charge advertisers for all of them.

America’s Audit Bureau of Circulations (ABC) has just modified its definition of a digital magazine in the U.S. and Canada to accommodate new reading devices such as the Apple iPad.

The new standards state that a replica digital edition must include a print edition’s full editorial content and advertising, but it no longer needs to be presented in a layout identical to the print version. Replica digital editions will continue to be included in a magazine’s circulation guarantee, or rate base.

Predictably, Wired magazine was the first publication to seek review of its iPad version, which will qualify as a digital replica edition under the bureau’s new guidelines. GQ has offered an ABC approved replica app for the iPhone and iPod Touch since December 2009.

Last week the ABC board gave its initial approval to the creation of new U.S. reports that better reflect a publication’s total audience across a range of products. As a result, publishers may begin reporting such items as:

• E-reader distribution averages
• Mobile app purchases
• Total paid and verified circulation emanating from multiple products, including branded print editions associated with the flagship publications.
• A new “Publishing Plan” executive summary box on the first page, noting frequency, delivery platforms, and distribution methods across a publisher’s various print and electronic editions.
• Continued use of Audience-FAX, the 2007 initiative that allows U.S. publications to report print and online readership figures, as well as Web site and audience data from comScore, Nielsen Online, Omniture, or other sources audited by ABC Interactive.
