Is NPR really considered "mainstream-media"? To me "mainstream-media" means the big for-profit corporate conglomerates. I bet not needing to make a 10-15% profit has much to do with it. Not only monetarily but also integrity("no worries a show/statement will alienate advertisers") and public perception. In fact I'd wager the not afraid of digital is a symptom of being a NPO.
