Magazine ad pages continued their slide in November. MediaBuyerPlanner reports that MIN's latest survey of ad pages sold in consumer magazines show that November ad pages were down 19.2% from November of 08. There are a few bright spots.

Of 171 titles MIN reported on, 84% saw ad pages decline for the month; 46% saw pages fall more than 20%, and 24.5% saw declines of 30% or more. Conde Nast’s W was one of the biggest losers, down 51% in ad pages, while Elle Decor was down 49%.

A few titles improved in November. People Stylewatch, for example, was up 32% in ad pages, and National Geographic was up 21.2%. Southern Living, More, Real Simple and Guns & Ammo also gained significantly in ad pages for the month.

MIN’s figures echo the third-quarter results recently released by the Publishers Information Bureau. Total ad pages for consumer magazines were down 26.6% for Q3 compared to the third quarter last year, per PIB. For the first half, ad pages were down 27.9%.

ZenithOptimedia’s latest ad forecast predicts that global ad spending will bottom out this year and will return to positive growth - though at just 0.5% - in 2010. Magazine advertising, however, will continue to decline for at least the next two years, ZenithOptimedia says.
