The station signed on the air on January 21, 1941; 83 years ago (1941-01-21).[5] Its original call sign was WBIR. The station's call letters came from Jesse W. "Jay" Birdwell, who founded the station. Birdwell sold WBIR in 1944. In 1949, it added an FM sister station, WBIR-FM at 103.5 MHz. At first, the two stations simulcast most of their schedules. But by the 1970s, WBIR-FM had its own Top 40 format and today is classic rockWIMZ-FM.
In 1956, WBIR added a television station, WBIR-TV channel 10. WBIR-AM-FM-TV were owned by a consortium headed by J. Lindsay Nunn and his son, Gilmore Nunn. The Nunn Family bought WBIR in 1944. In January 1961, WBIR-AM-FM-TV were sold to the News-Piedmont Company of Greenville, South Carolina. Soon afterward, News-Piedmont changed its name to Multimedia, Inc.
The company sold off most of its radio stations including WBIR-AM-FM, while keeping its television stations. WBIR-TV kept its original call letters but the radio stations were required to get new call signs. Through the years, 1240 AM has been called WEZK, WZEZ, WIMZ (call letters still found on 103.5 FM), WTXM and WJXB. In 2004, the station took its current call sign, WIFA.
