To the Best of Our Knowledge (TTBOOK) is an audio magazine of ideas — two hours of smart, entertaining radio for people with curious minds. It's sort of journalistic, but it's never about the president's speech to the U.N., weapons inspections in Iraq, or yesterday's stock market disaster. It's the kind of show that would spend an hour on advertising or on the roots of hip- hop. It might also spend an hour on hair. Or salt. Or pirates, road trips, house cleaning, animal intelligence, high energy physics, the afterlife, or how to say you're sorry ....
Each week, more than 2 million listeners across the country and around the world tune in to the Diane Rehm Show for a lively mix of current events and public affairs programming that ranges from hard news analysis of politics and international affairs to in-depth examinations of religious issues, health and medical news, education and parenting.

Each show includes dialogue with listeners who call, e-mail, or tweet to join Diane's virtual community and take part in a civil exchange of ideas.
