Wouldn't WPLM overlap coverage with WBRU too much ?
WXRV makes sense for the northern, western and northwestern suburbs, WPLM makes sense for the southern and southeastern suburbs, WBRU (or whatever it's called these days) covers nothing in the area that WPLM already does, except the southwestern fringe of the market. The problem is none of these signals is a major player in Boston proper. EMF can't get bull's eye in the Boston market unless it can pry a big signal with aging or otherwise undesirable to Madison Avenue demos and no sellable format hole available to it away from one of the big boys.
WZLX, maybe, if the programming wizards feel that '90-'00s rock is too splintered to become the cornerstone of the classic rock format going forward? Or is it too soon to be thinking that way, and does classic rock still have a few more profitable years left in it playing mainly 30-to-50-year-old-songs?
