A couple weeks ago, one of the Detroit pop stations mysteriously switched formats and started calling itself “Doug FM”. They described their new format, if I recall correctly, as being like you “dropped your iPod in a can of paint”. What it boils down to is that they don’t have a 25 song playlist of current music in some format. They play a variety of things from the 70s, 80s and early 90s (I haven’t heard more recent than that on there).
It turns out that Doug is part of a new breed that also includes Bob, Jack, Dave and other radio stations.
