NPR has very little enterainment. PBS and such has a bit more to capture a wider audience. I don't think its so much that the college educated don't watch pbs as much as more non college educated watch pbs and don't listen to npr. These are percentages of the audiences. Given that I catch npr all the time as I only seek elswhere on the radio when in the car if I just don't like whats on npr but I sorta got to go outa my way to catch npr. Also you have to catch or stream later like the new hour but news on the radio is throughout the day every day including rebroadcast of bbc.
