New York—The Business Information Network report, produced by American Business Media, is expanding into trade show revenue and attendance tracking. The new report, titled T-BIN, will use data collected by the Center for Exhibition Industry Research. The first T-BIN report, released last week, showed trade show revenue totaled $2.78 billion for the first quarter, up 5% from $2.65 billion in the year-earlier period. Trade show attendance reached 18.7 million in the first quarter, up 11% from 17.8 million in the first quarter of 2004. The BIN report also tracks ad revenue and pages for b-to-b publications, from information collected by IMS/The Auditor and PERQ/HCI for health care figures.
