It consists of fairly in-depth, thoughtful coverage of both domestic and worldwide news topics, as well as a tiny bit of political analysis on Mondays and Fridays. It almost never devolves into the breathless, “the world is about to end”-type coverage found on basically all cable news programs. Judy Woodruff and her team are really great. I dearly miss Gwen Ifill and Jim Lehrer.
The Economist is also a great resource, as has been pointed out by other commenters here. They publish an audio edition of each week’s newspaper, too.
