You are correct. Saga/Franklin Communications used to own WVKO-AM as well as Sunny 95.
In late 2002, Saga "swapped" 1580 for 107.9 with Stop 26/Riverbend, the company owned by Columbus attorney Percy Squires. Saga/Franklin continues to program the station with oldies, but the type of oldies B107.9 WODB plays have become more recent over the past year. Apologies for the use of an oxymoron.
After Squires and Stop 26/Riverbend filed for bankruptcy, Bernard Media ended up with Squires' stations in Columbus and Youngstown. The bankruptcy was what resulted in WVKO-AM going off the air for more than a year.
Saga/Franklin Communications also owns locally WJZA/WJZK, "Smooth Jazz 103.5/104.3," which were acquired from Scantland Broadcasting, a husband-and-wife ownership team which brought the format to Columbus in 1995. 104.3, licensed to Richwood, went on the air shortly before Christmas that year, and 103.5, a former oldies station in Lancaster, was purchased by the Scantlands a couple of years later. Saga then got the city of license moved to Pickerington.
I will leave it to other posters to fill in any missing details.
