(None of the magazines named in this article are necessarily the sources of declines at their respective publishing groups; they are simply some of the leading titles published by those companies.)

Among the "big three" publishers, Time Inc. is definitely faring the worst, with ad pages down 8.2% in the first four months of 2008 to 8,467. Conde Nast and Hearst experienced more modest declines. Conde Nast--which publishes Vogue, Vanity Fair, Glamour, GQ, Details and Portfolio--saw ad pages fall 2.9% to 11,961. Hearst--publisher of Good Housekeeping, Harper's Bazaar, Cosmopolitan and Esquire--saw ad pages slip 0.6% to 5,614.

Enthusiast and lifestyle publishers were not spared. Bonnier Magazine Group--which purchased a number of enthusiast titles from Time Inc. in 2007, including Field & Stream, Popular Science and Parenting--saw ad pages fall 9% to 4,759 in the first four months of 2008.

Hachette Filipacchi Magazines (publisher of Elle, Woman's Day, Home, Car and Driver, and American Photo, among others) fell 7% to 4,083. Hachette closed the print version of Premiere, an entertainment news title, in favor of online-only publication in March 2007; the decline in ad pages may reflect this move, at least in part.

Meredith Corporation--publisher of women's interest titles, including Better Homes and Gardens, Ladies' Home Journal and Family Circle, saw ad pages tumble 13.4% to 3,359.

American Express Publishing Corp., which publishes Travel + Leisure and Food & Wine, is down 5% to 1,280 ad pages. Source Interlink, which publishes Motor Trend, Automobile, Hot Rod and Soap Opera Digest, is down 17.1% to 1,828. Finally, Wenner Media, publisher of Rolling Stone, Men's Journal and Us Weekly, is down 9.1% to 1,186.
