Whenever public broadcasting is threatened by hostile politicians, the conventional wisdom is to circle the wagons and fire back. As a member of the public television community for almost 50 years, I would rather see today’s challenge as an opportunity to reassess public television’s goals and achievements. Perhaps we should do this every few years to make sure we haven’t gone astray in our aims and practices. In many ways I think NPR has surpassed its original goals and promises, but public television is another matter. We have accomplished many things.
