There’s a new radio format on the Canadian airwaves, and record labels aren’t exactly thrilled. The stations are called JACK or BOB. “JACK’s “brave” programming strategy is to ignore radio’s typically strict formatting and to play a variety of stuff on one format that you’d normally hear on, say, three: A bit of classic rock, some adult contemporary and a whole lotta ’80s hits geared primarily towards listeners in their upper 30s and early 40s.”
