"I am thrilled to have the opportunity to lead one of the world's leading providers of news, music and cultural programming on an interim basis and I look forward to working with my colleagues on the board and senior leadership team to help this great organization build on its success," Haaga said in a statement. He was not available for an interview Friday, NPR said.
Haaga has served as chairman of the board at the Los Angeles County Museum of Natural History and is the retired chairman of the Board of Capital Research and Management Company.
He succeeds Gary Knell, who is leaving after less than two years to become president and CEO of the National Geographic Society. Knell's predecessor, Vivian Schiller, resigned under pressure after calling the tea party racist.
The leadership change was announced as the board approved a fiscal 2014 budget that includes $178.1 million in operating and investment revenues and expenses of $183 million. NPR says its voluntary buyout plan is intended to reduce that deficit.
NPR distributes news, information and music programming to 975 public radio stations, reaching 27 million listeners a week.
