New York—American Business Media officially debuted Friday the new reporting model for its Business Information Network, which tracks b-to-b print advertising sales. Ad pages dipped 0.73% for the first two months of 2005 compared with the same period last year, according to the new reporting system. In the same time frame, ad revenue increased 2.23%. BIN reports now examine 22 SRDS magazine categories rather than advertising categories. IMS: The Auditor tracks advertising in most markets, and PERQ/HCI handles the health care figures. The new model boosts the database from 800 b-to-b publications to more than 1,600. "This enhanced system is more representative of the size and scope of the business-to-business publishing universe," said Gordon T. Hughes II, president-CEO of American Business Media. "It is the first step to offering a complete analysis of business-to-business media that will soon include several media platforms."
