An earlier trade show for resellers, corporate managers and technical professionals from CMP Media LLC (later United Business Media). First held in New York in 1983 with 120 exhibitors and 9,600 attendees, the show grew from the personal computer's early years to 550 vendors and more than 86,000 attendees by 1999. By 2002, attendance had dropped to half that number due to the economy, and PC EXPO became the exposition side of TECHXNY, an annual fall technology event in New York. In 2005, in partnership with H. A. Bruno, LLC., TECHXNY evolved into C3 Expo (Corporate and Channel Computing Expo). See
