Evolving from the optional meetings that followed the annual multi-client studies on The Role of Executive Briefings, the Association of Briefing Program Managers (ABPM) was formed in March, 1994. ABPM is comprised of over 400 members from more than 100 Fortune 500 companies. About 10% of that membership consists of supplier members who are vendors who must be nominated by company (briefing professional) members who are satisfied with their services.
