NPR recently announced a downturn in corporate sponsorship. The falloff in revenue has led to speculation about cuts in staff and programing. Gary Knell is NPR's president and CEO. He succeeded Vivian Schiller, who was ousted after the release of a tape in which an NPR executive disparaged conservatives and in the wake of firing Juan Williams. These incidents nearly cost public broadcasting its federal funding. Knell joins Diane to discuss NPR's future as it faces many challenges, including financing, competition for audience and changing technology.
