These kinds of sudden changes are rarely just what the press releases suggest they are. In non-comm radio we've seen some shady and quick sell-offs in Houston and Miami recently, that also sharply reduce the amount of non-comm programming, and make room for even more of the same ol' time religion you already hear from eight other stations. Remember, these are stations that thousands of people invest in as members. They are not considered by their listeners to be merely commercial real estate that the rest of the dial has become since deregulation of their public service requirements.
I suspect the majority of KLPU's listenership and revenue was not from its jazz programming, since they've been reducing it on weekends in the past year. So dropping the news and going fulltime jazz ("because Seattle is such as jazz mecca!") is a lot more cynical to my ears than anything I'm writing here. Like most hybrid music and news NPR affiliates, the bulk of the audience and underwriting support comes from the talk and NPR programming, and their local inserts in it - not from the music dayparts, nice as they may be.
As much as I personally welcome a fulltime jazz outlet, and perhaps some new air talent, I don't think UW would go to this trouble, and make such a sudden move an hour before the university regents met to vote on it, if everybody was being honest and transparent, and had the listeners' interests as their priority.
Competition between two full power stations with local newsrooms gives us better radio. The KUOW and KPLU audiences do not overlap as much as you commercial observers might suspect, from what the KPLU GM confided to me a couple years ago. And a recent trend showing gains most months in KPLU's audience share suggest a lot of it may be at the expense of KUOW, since KUOW started to chop up all of the national news programs to insert legal IDs and slogans every five minutes, and pretend to be hosting national shows, instead of letting the actual national hosts take care of the interstitials between the news features.
Just listen, for heaven's sake.
