New York--B-to-b ad pages were up 3.8% and ad spending soared 10.1% last year, topping $10 billion for the year, according to a Business Information Network report released by the American Business Media. The top five ad page categories showing increase over 1999 were: finance, business and advertising (31.0%); telecommunications (21.3%); manufacturing and electrical equipment, materials and components (8.6%); services, direct response and classified (3.3%); and drugs and toiletries (1.5%). Ad pages were down 8% in January, compared with a year earlier, and ad spending was down 3%. Telecommunications increased 10.9% over last year, and travel increased 4.3% over last year, but the remaining 10 media categories were all down. Gordon T. Hughes II, president-CEO of the ABM, said the numbers reflected the softening ad economy and weren't as bad as the association expected.
