Recent articles in Washington Post about the DC NPR news/talk station, WAMU 88.5 FM are interesting in light of the turmoil in recent years at DC's WPFW (89.5 FM) and other Pacifica stations (NY, Berkeley, LA, and Houston).
It boils down to this -- when new management decides to become more "corporate" (I use that term loosely) and tries to appeal to a more upscale (i.e., richer) audience (and advertisers/underwiters) and make organizational and schedule changes to focus, streamline, and dictate policy, they will encounter resistance.
Not all change is for the better. On the other hand, keeping the status quo may ignore a shifting environment.
Public and community radio has a different relationship to listeners and volunteers, than commercial broadcasting.
I'll leave it at that, for the time being, because such a discussion would require many hours of thought and discussion. [It really touches on the area of organizational development (OD), which I've not read up on in many years.]
