The appointment takes effect next month. Aflac has taken its time replacing its last CMO, Jeffrey M. Herbert, who left last fall after just a year on the job.
Mr. Herbert famously said he planned to ditch Aflac's duck icon, created by longtime creative agency Kaplan Thaler Group, but later reversed his position and vowed the duck would stay.
Mr. Charney most recently served as senior VP-CMO for QVC, and earlier he held senior roles at Rockwell International and Raytheon Co.
"Jeff Charney is a proven leader with cutting-edge experience in brand development, creative consumer and product marketing, and strategic business development," Aflac's president-chief operating officer, Paul S. Amos II, said in a statement. "As we continue to promote the understanding of Aflac products and services to employers and consumers, I am confident that Jeff will be a significant asset in fortifying our position as the market leader of supplemental insurance in the United States."
