LAS VEGAS >> The Las Vegas Convention and Visitors Authority is bringing back its classic “What happens here, stays here” ad campaign.

Visitors Authority spokeswoman Courtney Fitzgerald says the first national commercial with the tagline will air on September 30.

Tourism officials have been giving the slogan a rest since the summer of 2012.

Instead, they have been promoting the hotel reservation website lasvegas.com. Among other ads, tourism officials filmed commercials with late-night comedian Jimmy Kimmel, who played a character LasVegasdotcom who’s constantly mistaken for the travel website by the same name.

The “What happens here, stays here” ads present Sin City as a place where visitors can do things they would never want their friends and family back home to find out about.
