Titan Worldwide and TH Properties have launched an outdoor and mobile advertising campaign that uses bluetooth technology, Media Week reported.

Consumers with bluetooth-enabled phones that pass by Titan posters in Philadelphia's Center City rail station will be invited to download a 30-second video clip about TH Properties. The Bluetooth campaign invite is activated when a consumer passes within 150 feet of the interactive billboards.

"Bluecasting [the name of the specific bluetooth technology Titan used] is an effective way of connecting with the thousands of commuters that travel through Suburban Station each day and a creative way of adding value to the marketing opportunities in Philadelphia," Don Allman, CEO for Titan, told Media Week.
