The "Jack" stations are nationwide and owned by the same company. They don't have DJs, per se, just a lengthy playlist and some comedic bumpers for the adbreaks. There's about a dozen Jack stations, "Playing What We Want (TM)" plus a few knockoffs plus Dave FM, Bob FM, and so on. Incredibly, this is a Canuckistan Innovation imported to America, like Pamela Anderson.
