WLAC in Nashville, TN, has traditionally traced its founding to November 24, 1926. That was the day the station made its first broadcast under the WLAC call sign. However, Federal Communications Commission (FCC) records list WLAC's "Date first licensed" as September 11, 1925, reflecting the initial license date for station WDAD, which was consolidated with WLAC in 1927.
WDAD was first licensed in September 1925 to "Dad's Auto Accessories (Inc.)" at 160 Eighth Avenue North in Nashville. It made its debut broadcast on September 14. WLAC was first authorized in November 1926 and was owned by the Life & Casualty Insurance Co., with its call letters chosen as an acronym for the owner's name. Studios were located on the fifth floor of the Life and Casualty building in downtown Nashville. WLAC initially operated on a timesharing basis with WDAD on 1330 kHz.
In mid-1927, Dad's Auto and Life & Casualty formed a partnership to operate their combined stations as WDAD-WLAC jointly. The following November, Life & Casualty purchased WDAD's interest in the combined stations. It announced that, effective November 21, 1927, the call letters WDAD would be discontinued and the station would operate only under the call letters WLAC.
