At the end of the eighties, KC-101 was a powerhouse with a format that was more of a catch-all than the contemporary hits we know today. The format has fragmented. There was no hip-hop station like 93.7 and 94.3 was just getting started without the sales LMA it has today with Cox.
Adult contemporary formats like WEBE 108 seem to have taken many of those heritage listeners from back in the day. Thanks to its big signal, KC-101 used to have huge shares in other markets like Bridgeport and Danbury (before 98Q), where they have seen similar shrinkage.
Remember Dr. Chris? Get a morning show with some strong branding and you get a lot of momentum. People talked about him while he talked to his imaginary friend Hozay! Not to knock the present morning show, but it is certainly not promoted the way it was.
The presentation has also gone through changes over the years, to the point where listeners can start wondering what happened to their station. At one point some time ago, KC-101 shed air talent completely only to return with a reshuffled version of its former self... although less extreme than their sister 104.1 in Hartford.
It still shares the CHR format with WKSS... but there's less to share now than 1989. KISS has seen its home base (Hartford) erode, too. CHR has taken hits in places like New London at Q-105. It's not just New Haven.
I'm sure Clear Channel cost-cutting is a factor, too. So, what HASN'T happened?
