Clear Channel, (NYSE: CCU) the media conglomerate with a huge outdoor billboard business, has big hopes with mobile marketing for 2008. It has updated 1,000 of its venues to take advantage of what what the company called “Outdoor 2.0,” a vision of the mobile as a remote control for consumer interaction…essentially using texting or Bluetooth, reports AdAge. It has partnered with mobile marketing company Qwikker to include a call-to-action element in each campaign. In NYC on some bus shelters, for example, consumers had to choose to download video clips from Discovery shows. For Pepsi, ads in airports asked consumers to subscribe to downloads from this year’s Pepsi Smash concert series. Saul Kato, founder and CTO of Qwikker, said the company tracks about 800K mobile-phone interactions per day, a number he expects to double by the end of Q1 next year, the story says.
