The audit also confirms that CES attracts business leaders from diverse areas including entertainment, retail, education, engineering and venture capital industries. This year, more than 12,000 buyers, 6,000 manufacturers and 2,800 engineers came to CES along with more than 6,000 attendees from the software development/publishing, content development and entertainment industries.

Each year, influential media and analysts attend the show to report on the latest products and trends in the consumer technology realm. The 2009 CES drew more than 4,500 media and 1,500 financial and market analysts.

The 2010 International CES is scheduled for January 7-10 in Las Vegas.

"This audit report confirms that the 2009 International CES succeeded, despite an economic downturn, in attracting top executives, retail buyers, content providers, entertainment executives, venture capitalists, engineers, government officials and media from around the globe," said Gary Shapiro, president and CEO, Consumer Electronics Association (CEA), producer of CES.

VERIS is certified by the Exhibition and Event Industry Audit Commission to perform audits. The VERIS audit differentiates the International CES from other industry tradeshows in that each CES attendee is only counted once, and only sold exhibit space is used to calculate show size, versus other events that include complimentary and bartered space and show usage space such as registration areas.
