NPR is celebrating its 50th anniversary, so we're spending some time thinking about what the next 50 years have in store. Journalists at NPR headquarters and at member stations are grappling with a lot of questions: why public radio sounds the way it does, questions about objectivity and who it serves, and questions about the best ways to deliver information to audiences, wherever they are.
