HEAR THEIR SECRETS

A billboard to promote the HBO series “Big Love” in Los Angeles has jacks for headphones, so passers-by can hear its messages.



To promote the new season of "Big Love," a drama about a polygamous family in Utah, HBO is installing billboards in New York and Los Angeles that feature headphone jacks that allow passers-by to plug in and listen to people confess secrets.
The campaign, by BBDO New York and other shops, is based around the tagline, "Everyone Has Something to Hide," and also includes a microsite and performing street teams in major cities.
