New York—Ad revenue for b-to-b magazines was flat in the first two months of this year, while ad pages fell 1.4% from the year-earlier period, according to estimates released Monday by American Business Media’s Business Information Network. “We finished 2005 with growth that was better than we expected,” said Gordon Hughes II, ABM president-CEO, in a news release. “This year may be starting slow, but we still expect to see growth of 5%.” B-to-b ad pages dropped 1.8% in January, compared with the year-earlier period, and fell 2.3% in February. The downward trend in b-to-b ad pages followed an upswing in 2005 in which ad pages climbed 3.9%. Some of the stronger revenue categories in January and February included Aviation, Aerospace & Military (up 33%) and Resources, Environment & Utilities (up 18%). Automotive was up 8%. Both the Transportation/Logistics and Travel, Business Conventions & Meetings categories were down 12% through February.
