Has nobody noticed that there's been some movement in the ratings? I think this is the first book I've ever seen KUOW at the top. KQMV down to third, KRWM has popped up recently.
Who cares about 6+ anyway? They don't mean anything and billing is not based off of them. Remember, radio is a business (a very rough and tough business), and all businesses are about making money.
Then again, when you have a non-commercial station at the top of any list, regardless of the criteria, it's interesting. To me, it says "radio is a business" only matters to the people in radio. The listeners don't care. If the only thing that matters is making money, it's possible that the listeners may prefer a station where there's a slightly different goal. Not to say non-commercial broadcasters don't care about money. But it's not their only motivation.
Take a listen to KUOW right now and tell me how often they're running promos and mentions asking for money. It's about 982x per hour.
