Listening to their online stream, there is a change during the commercial breaks. Instead of a Brian James-voiced liner, "You're listening to (insert show here) on 107.9 The Link, more next..." followed by an ad for a Link program, then a song, it is now a generic, snazzy jazz tune. And it's the same exact one used at every single commercial break.
The reason I'm bringing this up is because - at least on their Internet stream - they're no longer promoting the other programs on the station.
Let the speculation... continue.
