The 550 AM frequency in Georgia was originally allocated to Atlanta and used by the Atlanta Constitution's WCON-AM. In 1951, the Constitution's broadcast and newspaper properties were purchased by crosstown rival WSB. The 550 AM license was then reassigned to Gainesville. 

​

WDUN AM 550 and WDUN FM 102.9 are divisions of Jacobs Media, a family-owned media company based in Gainesville, Georgia. Jacobs Media also owns 94.5FM The Lake and AccessWDUN.com.

​

Jacobs Media was founded in 1949 by the late John W. Jacobs Jr., a successful businessman, and philanthropist. Under his guidance, Jacobs Media brought North Georgia its first FM radio station, its first cable company, and the region’s first online newspaper. 

​

Today, WDUN AM/FM is a news/talk station, offering a mix of local and syndicated talk, while sister station The Lake offers adult contemporary music of the 80s, 90s, and today.

​

In 1999, Jacobs’ son, John W. “Jay” Jacobs III, the current president, and CEO launched AccessNorthGa.com, the region’s first Internet news service. In April 2015, the website was rebranded as AccessWDUN to combine the site’s news coverage with the rich history of WDUN radio.
