As networks continue to roll out new shows, Fox turned to an experiential marketing display in midtown Manhattan, 5th Ave. and 5th St. on Friday, hoping to give a lift to drama "Lie to Me," which has its season debut Sept. 28.

The network, in partnership with promotions shop Pop2Life, installed several interactive billboards on 5th Avenue, where passersby were encouraged to confess lies they have told by sticking a handwritten postcard on the displays, tabbed "Confession Walls."

A sweepstakes, where a winner would get a trip to the show's set, was also involved in the stunt.

"Lie to Me," now entering its second season, involves the paranormal. A psychologist, who detects personal thoughts by reading face and voice, including prevarications, helps law enforcement in various criminal investigations.

Its debut at 9 p.m. should get a bump through a lead-in from big-time Hugh Laurie hit "House." "Lie" stars Tim Roth, Kelli Williams, Monica Raymund and Brendan Hines.

Pop2Life, with offices in New York and Los Angeles, has worked on behalf of multiple other entertainment clients on grassroots efforts.
