Early years

This station started out as part of a radio experiment by Mercer University professor C.R. Fountain's physics class in 1910. On October 30, 1922, Mercer obtained a commercial license under the call sign WMAZ. The university soon found itself in over its head operating a radio station. In 1927, it sold WMAZ to the Macon Junior Chamber of Commerce, forerunner of the Macon Jaycees.

A group of Macon businessmen formed the Southeastern Broadcasting Company and leased the station in 1929 before buying it outright in 1935.^[2] In the 1930s, WMAZ was a daytimer, broadcast on 1180 kilocycles, first at 500 watts, and later at 1,000 watts, but required to sign off at sunset to protect WCAU in Philadelphia. In 1937, WMAZ became a CBS Radio Network affiliate, carrying its schedule of dramas, comedies, news, sports, soap operas, game shows and big band broadcasts during the "Golden Age of Radio." It broadcast the Soap Box Derby live. By the late 1930s, WMAZ was permitted to remain on the air after sundown, but at reduced power to protect WCAU.

In 1941, with the enactment of the North American Regional Broadcasting Agreement (NARBA), WMAZ moved to its current 940 kHz, a better spot on the dial.^[3] The power was boosted to 5,000 watts around the clock, and by 1950 it increased to 10,000 watts.

FM and TV stations

In 1947, Macon's first FM station signed on, 99.1 WMAZ-FM (now WDEN-FM).^[4] WMAZ-FM mostly simulcast its AM sister station for its first couple of decades. In 1953, the Southeastern Broadcasting Company added Macon's first VHF TV station, Channel 13 WMAZ-TV.^[5] Because 940 WMAZ was a CBS affiliate, WMAZ-TV also ran CBS TV shows, with a secondary affiliation with ABC and the DuMont Television Network.

In the 1950s, as network programming moved from radio to TV, WMAZ-AM-FM switched to a full service middle of the road format of popular adult music, news and sports. In the late 1950s, WMAZ-AM-FM-TV produced middle Georgia's first radio-television simulcast for the 24th Annual Bibb County Spelling Bee. In 1958, 940 WMAZ's daytime power was boosted to 50,000 watts.^[6] That made it the second-most powerful station in Georgia, after WSB 750 in Atlanta, powered at 50,000 watts around the clock. In the 1960 edition of Broadcasting Yearbook, an advertisement said 50,000 watt WMAZ is "the only station to cover completely the rich, 31-county Middle Georgia market."

Ownership changes

Southeastern sold WMAZ-AM-FM-TV to Southern Broadcasting Corporation in 1963, which merged with the News-Piedmont Company to form Multimedia, Inc. in 1967. In 1974, WMAZ-AM-FM-TV moved to a new studio facility on Gray Highway in Macon. Throughout the 1980s, the station had an adult contemporary format until 1989 when it switched back to its former MOR format.

Multimedia merged with Gannett in 1995. Gannett had by this time decided to pull out of radio, concentrating on its TV stations and newspapers. It sold off the radio stations in 1996. The new owners changed AM 940's call letters to WMWR (standing for Macon-Warner Robins), but a year later, the station was sold as part of a group purchase by U.S. Broadcasting. In 1998, the station changed to its current call sign, WMAC. The call sign not only stands for Macon, but are a nod to the heritage call letters the station used for three-quarters of a century.

In 2002, U.S. Broadcasting sold this station as part of a group purchase by Cumulus Media. In 2015, WMAC switched To Westwood One News from ABC News Radio due to a corporate change by Cumulus Media. In August 2020, Westwood One News shut down; so WMAC aligned with Fox News Radio for national news. As the news department was scaled back due to budget cuts, news and weather updates began to be supplied by former sister station WMAZ-TV Channel 13.
