The original owners were Kentucky broadcasters, Bill Betts and Gilmore Nunn, who vacationed in Marathon.
Radio Marti is actually on Sister's Creek Island, adjacent to Boot Key and inside the Marathon City limits.
The station was most recently owned by Jonathan Smith's Choice Radio Keys Corporation.
Due to an inability to pay outstanding debts, the company assigned the licenses of WFFG and sister stations WGMX, WKEY-FM, and WKEZ-FM to a trustee on June 4, 2018, to be sold for the benefit of creditors.
A sale of WFFG and WGMX to Joseph Nascone's The Great Marathon Radio Company was consummated on September 14, 2020, at a price of $35,000.
