WIVK-FM has by far been a much more dominant station (it doesn't hurt that it's in a smaller market with fewer viable signals than Greensboro/Winston-Salem.) WIVK-FM has been the #1 station in Knoxville since 1980 (you could go further back if you count the audience of its former, mostly-simulcast AM sister at the time.) It peaked with a 33.4 share in 1991 (FM alone). The Winter 2017 book and its 9.7 share is the first time the station has been in single digits since 1973. WIVK-FM had a 17.1 share just two years ago - a decline that steep is very uncommon, especially given there has not been much in the way of wholesale change in the station's formatics or presentation.
