PBS, the antidote to "Ice Road Truckers"

PBS President Paula Kerger was in Knoxville recently, and chatted with Metro Pulse. One topic: Why PBS remains unique in the world of TV. "There are just so many options, and so many channels have pursued different niches. ... Other channels, like the Learning Channel, Bravo, and the History Channel started down the path towards being a commercial version of public broadcasting, but they’ve all moved away from it. ... The History Channel’s name franchise is now Ice-Road Truckers, you know? So we’re still providing something no one else is."
