Well, so much for the hand wringing. After concerns among exhibitors and attendees that changes implemented for the 2001 National Systems Contractor Association show in Orlando–namely larger booths–would negatively affect attendance and quality, this year’s show attracted the largest crowd yet. Nearly 11,000 people attended the Systems Integration Expo™ March 8-10, an increase over the 10,000 people at the 2000 show. More than 500 exhibits featuring audio, video, security, lighting, data cabling and other commercial electronic systems technology were highlighted at the 21st annual event held at the Orange County Convention Center.

"The 2001 NSCA Expo was a spectacular success. The show exceeded our expectations on many levels, not the least of which was a new record for attendance," said Andy Musci, NSCA Expo Chairman and President of Altel Systems in Brewster, NY.

Much of the show’s success was attributed to the exhibit floor’s new layout. Larger booths and limited audio created an all-new look to the floor, both offerings available for the first time since the NSCA Expo’s inception. "We believe that the new, expanded format will set a benchmark for future shows and we look forward to continued successes with the NSCA filling a strong leadership role both within our industry and also participating as an agent providing outreach to related businesses and industries," said Musci.

In addition to the 10’ x 15’ booth, the NSCA added two more booth sizes, a 10’ x 30‘ and a 20’ x 30’. The availability of more space assisted exhibitors who in the past had difficulty displaying working technologies in a small space. Audio limited to 72 dBA also allowed exhibitors to more effectively demonstrate their product, but not to the detriment of the show. Levels were strictly monitored so one-on-one conversations could be easily conducted.

NSCA Expo education also had a banner year, with over 1,800 class tickets sold. "NSCA education couldn’t have been better," said Katie Chism, NSCA manager of educational programs. "The attendance was strong and we owe much of its success to the quality and dedication of our instructors." More than 400 hours of technical and business education took place at Expo, starting March 5 and ending on March 11. Tracks included the Integrated Systems Application Seminars, Audio, Video, Security/Lighting, Connectivity, Business and Sales.

The 2002 NSCA Expo is April 25 — 27 at the Colorado Convention Center in Denver. More information will be available at www.nscaexpo.org later this spring.
