Huh—I judge PBS much more valuable to me, these days. Kids are a big factor in that, but also NPR's news is largely pretty poor—it's all horse-race shit and campaign Monday-morning quarterbacking around elections, the campaigns for which are now so long that they seem to be happening more often than not, and they continue to be blind to all kinds of issues and events generally—when it's not just re-broadcasting the BBC, and two of my favorite programs are gone now with nothing I consider anywhere near as good to replace them (Car Talk, and old-school A Prairie Home Companion, i.e. atheist Sunday church service). Some bright spots remain (On the Media), sure, but largely not stuff I care about or else programs that I think are simply bad.
They also spend a ton of time on ads (if you include promoting their own programs, especially).
I don't love a lot of PBS' current programming, but their historical material is a goldmine.
