Pirkle just sold WNFZ Thursday (3/21) to Midwest who immediately re-formatted it as Jack FM. Will be interesting to see how well it does this time. When 95.7 flipped from oldies to Jack, they lost half of their audience (including me). Midwest operates what seems to be the only successful Jack station in the state WCJK Murfreesboro (Nashville). Knoxville dropped Jack-95.7 is now "Duke" and country while parallel slave 106.7 has been sold to Blue Ridge. Three stations have run Jack in the Chattanooga market and all have dropped it. Active rock is not dead in the Knoxville market, it is now airing on WVLZ 1120 Maryville and two translators.
