CES Clamping Down On Show Floor Photography?

Even at America's largest consumer electronics trade show, many CES attendees fear copycats more than they love publicity.

According to the show's FAQ, all imaging equipment must be registered and stickered, and journalists who take "inappropriate" pictures of exhibits — despite them being seen by thousands of showgoers — may be reported to security:

"Are cameras allowed on the show floor?

Media are required to obtain passes/stickers for their camera equipment. Exhibitors and attendees may take pictures within the show for purposes of company or annual reports, company media pieces, marketing materials, etc. Under no circumstance will anyone be permitted to take pictures of an exhibitor's product without the permission of the exhibitor. Many products on display at CES are unique, innovative, one-of-a-kind or prototype items. Exhibitors have the right to report to security any instance of inappropriate photographing of company products or displays."

Last year, when people tried to prevent us taking photographsof their stuff, a CES spokesperson told us she hated it when exhibitors did this.

"We've always welcomed photography on the floor," she said at the time. "Show shots are encouraged."

Not any more. What changed?
