Its daytime coverage area is not as large as 50,000-watt AM stations in other parts of the country due to Georgia's poor ground conductivity; as such, a number of outer Atlanta suburbs only receive a grade B signal.

A transmitter had been ordered, but facing a delay, the newspaper arranged for the equipment used by Gordon Heidt for his amateur station to be temporarily installed.

A broadcasting license was normally needed before a station could go on the air, but it was arranged to have an initial telegraphed authorization, which was sent by the Department of Commerce on the evening of March 15, 1922.

[8] In September 1922, the Department of Commerce set aside a second entertainment wavelength, 400 meters (750 kHz) for "Class B" stations that had quality equipment and programming.

[15] However, at the end of July, WGM permanently ceased operations, which gave WSB exclusive use of the assignment.

[16] The station carried NBC's dramas, comedies, news and sports during the "Golden Age of Radio".

[17] On November 11, 1928, under the provisions of the Federal Radio Commission's General Order 40, WSB was reassigned to a "clear channel" frequency of 740 kHz.

In March 1941, as part of the implementation of the North American Regional Broadcasting Agreement (NARBA), WSB moved to 750 kHz, where it has been heard ever since.

Part of WSB's programming was southern gospel music, gaining popularity throughout the region, with shows hosted by Charles Davis Tillman.

The Shelby Star newspaper, in an issue dated November 1985, wrote that the talented Dan Hornsby, after the 1929 crash of the stock market, found himself working no longer for Columbia Records.

Wright Bryan, a WSB news reporter as well as managing editor of the Atlanta Journal, was also a stringer for NBC during World War II.

Afterward, the WSB stations were housed in a Colonial-style mansion with its interior specially built for broadcasting, informally known as "White Columns".

In 1998, all of the Cox's Atlanta radio stations, as well as WSB-TV, moved into a new "Digital White Columns" on the same property.

During its early years, when few people had FM radio receivers, WSB-FM mostly simulcast the programming on WSB.

As network programming moved from radio to television in the 1950s, WSB-AM-FM began airing a full service, middle of the road format of popular music, news, sports and information.

Just as WSB aired NBC Red Network radio programming, WSB-TV was originally a primary NBC-TV affiliate.

WSB formerly broadcast in AM stereo using the Motorola C-QUAM system during the 1980s, a period when music could still be heard on the station.

[23] On August 16, 2010, WSB began a full-time simulcast on co-owned WBTS 95.5 FM, which previously played rhythmic contemporary music under the branding "95.5 The Beat".

Weekdays begin with Atlanta's Morning News, anchored by Chris Chandler, Judd Hickinbotham and Cheryl Castro.

In middays, afternoons and early evenings, local talk hosts include Erick Erickson, Mark Arum, Eric Von Haessler and Shelley Wynter.

Weekends feature shows on gardening, home repair, cars, real estate, health and money, some of which are paid brokered programming.
