The lasers can do anything you want them to, explains Bob Pittman, the CEO of Clear Channel, during a visit to his midtown Manhattan office. The tour includes a hallway that changes stations as you walk along it, touch-activated lasers that let you play different musical notes, and a holographic Ryan Seacrest who greets you as you step off the elevator. Pittman had been CEO of AOL, Six Flags, and MTV before he took over at Clear Channel, and understatement has never been his style. But iHeartRadio, the digital arm of Clear Channel’s sprawling media empire, seems to have found a way to thrive at a time when its peers in the record industry are struggling to make the transition into the mobile age.
