All five stations share studios located at the Granby Building in Cayce and the WISW transmitter is in West Columbia.
By the 1980s, WOIC's ratings started to decline due to the growth of new urban contemporary outlet WWDM.
In the fall of 1989, it was announced by then-owners Price Broadcasting that the station would change over to a simulcast of WOMG-FM's oldies format.
In order to prevent any community backlash, an arrangement was worked out with 1230 WODE to move the staff and programing over to their station.
In August 1999, Imus was dropped for "Good Morning Columbia", hosted by longtime former WSCQ air personalities Bill Benton, Doug Enlow, and Gene McKay (who died in 2007).
Both McKay and Benton began in the Columbia market on the original WIS until leaving in the mid-1970s for WSCQ, which they were part-owners.
Benton's son Charlie, a WISW sales manager, joined the show in 2007 after McKay's death.
In addition to "Good Morning Columbia", the station featured a rotating "Local Angle" hour with nationally syndicated Neal Boortz, Bill O'Reilly, Sean Hannity, Laura Ingraham, Rollye James, and Jim Bohannon.
WVOC had been the flagship of the Gamecocks for 48 years, but owner Clear Channel Communications was not willing to move any Gamecocks-related programming to the more powerful FM stations in its Columbia cluster.
