An annual survey by the Audit Bureau of Circulations (ABC) and ABC Interactive reveals more publishers are gaining more confidence in the mobile market.

The survey, entitled Going Mobile: How Publishers Are Maturing and Monetizing Their Offerings, shows the number of publishers who say they have "a well-developed plan for the mobile market" rose to 59% from 28% in 2009. Meanwhile, 67% said it was "important to their strategic future to earn revenue from both ads and subscriptions", noted ABC.

The survey also highlights that 85% of survey respondents said they currently have mobile content for smartphones, e-readers or tablet devices, up from 76% last year.

Newspapers (88%) were most likely to have mobile initiatives in place, followed closely by consumer magazines (83%) and business publications (79%), according to the audit bureau.

The study revealed that publishers "had mixed feelings about how to best charge consumers for accessing content on multiple platforms. Forty percent said readers should pay one price and receive access to all platforms—print, web, mobile—while another 40% said readers should pay more for each additional platform."
