As of the 2007 baseball season, WMFS has become the home of St. Louis Cardinals broadcasts in the Memphis area.

It is one of five radio properties in the Memphis market held by Audacy; the others are WLFP, WRVR-FM, WMC, and WMFS-FM.

The Memphis Press-Scimitar bought the station in 1937 and changed the letters to WMPS, moving it to Columbia Mutual Tower on Court Square.

Kay Starr and Eddy Arnold gave some of their earliest performances on WMPS, which also aired The Carter Family, Jimmie Rodgers, Bill and Charlie Monroe, and Bob Wills.

"Smiling" Eddie Hill of The Grand Ole Opry went to work at WMPS in 1947, leading the house band that included Ira and Charlie Louvin, who wrote songs for Bill Monroe, Emmylou Harris, James Taylor, Mark Knopfler, Alison Krauss and Ray Charles.

Johnny Cash later recalled hearing the Eddie Hill band featuring the Louvin Brothers on the radio, and program director Bob Neal played his "Hey Porter" and "Cry!

WMPS soon played the "Memphis Sound" of blues, soul and funk Roy Mack worked with the Devilles and changed their names to The Box Tops.

He was fired from WMPS because of conflict of interest and suspected payola, but WHBQ hired him, eventually winning the Top 40 wars before the format left AM.

In 1992, WKDJ began simulcasting FM sister station WODZ and their oldies format (which later flipped to country in February 1993).
