The video game industry's 2006 E3 Expo trade show in Los Angeles is getting a make-over -- banned are the swarms of sexy, semi-clad "booth babes" that in years past took the unveiling of new games and technology to titillating new levels.

Rules prohibiting the use of scantily clad young women to peddle video games are nothing new, but the handbook for this year's show in May outlines tough new penalties, including a $5,000 fine on the spot for the booth owner if the "booth babe" is semi-clad.

"What's new in 2006 is an update and clarification of the enforcement policies; as we do from time to time, we have taken steps to ensure that exhibitors are familiar with the policy and how it will be enforced," Mary Dolaher, E3 Expo show director, said in an e-mail.

She did not comment on the reasons for the change.

The video game industry has come under fire from federal and local politicians, who want to limit sales of violent and sexually explicit games to minors.

The handbook from the Entertainment Software Association, the show's promoter, says: "Material, including live models, conduct that is sexually explicit and/or sexually provocative, including but not limited to nudity, partial nudity and bathing suit bottoms, are prohibited on the show floor, all common areas, and at any access points to the show."

Exhibitors would receive one verbal warning when a violation occurs. Upon a second violation, the ESA said it would impose a $5,000 penalty, payable immediately on the site. It would also require that models comply with the dress code before returning to the floor.

ESA said it has sole discretion to determine what is acceptable.
