Wendy's is an American international fast food restaurant chain founded by Dave Thomas on November 15, 1969, in Columbus, Ohio. Its headquarters moved to Dublin, Ohio, on January 29, 2006. As of December 31, 2018, Wendy's was the world's third-largest hamburger fast-food chain with 6,711 locations, following McDonald’s and Burger King. On September 29, 2008, the company merged with Triarc Companies Inc., the publicly traded parent company of Arby's; Wendy's headquarters remained in Dublin. Triarc then became known as Wendy's/Arby's Group, and later as the Wendy's Company following the sale of Arby's to Roark Capital Group.
