This is pretty interesting--from a press release:
The Convention Industry Council (CIC) unanimously approved the National Business Travel Association (NBTA) as its newest member organization at its board of directors meeting on March 10, 2005. With the addition of NBTA, CIC's 31 member organizations represent more than 100,000 individuals as well as 15,000 firms and properties involved in the meetings, conventions and exhibitions industry.
"We are confident that NBTA will bring a fresh perspective to the table," commented Mary E. Power, CAE, president and CEO of CIC. "In addition, as travel managers increasingly become involved in corporate meetings, NBTA members will benefit from having this direct link with CIC and its member organizations."
