I'm not sure if WW1 handles the nationally syndicated "Jack" adult hits format. But it's on numerous stations, even in some medium markets. I think WGTZ Dayton, WXMA Louisville and a Cumulus-owned translator at 102.5 in Kansas City all run the national Jack format.
Of course, it doesn't sound like its a national feed because there are no DJs. The sarcastic liners are all there. If the station has sold enough spots, it will break at certain times of the hour. If it hasn't, it stays with the network and we hear the 4 1/2 minute song that goes where the spot break would otherwise be.
