Wendy's is a major American fast-food chain, best known for its square-shaped hamburgers, Frosty desserts, and diverse side options like baked potatoes and chili. Founded by Dave Thomas in 1969 in Columbus, Ohio, it quickly became one of the largest hamburger chains in the U.S., trailing only McDonald's and Burger King. The chain's iconic logo, a smiling redheaded girl, was modeled after Thomas's daughter, who also inspired the restaurant's name. Wendy's is known for its focus on quality, highlighted by its "fresh, never frozen" beef patties. Over time, it gained popularity not only for its menu but also for its advertising campaigns, including the memorable 1980s slogan, "Where's the Beef?" Dave Thomas, who appeared in over 800 Wendy’s commercials, became a beloved face of the brand until his death in 2002. Wendy's continues to expand globally, and its corporate headquarters are now in Dublin, Ohio. The company has also been involved in philanthropy, notably with the Dave Thomas Foundation for Adoption, which supports adoption causes. Today, Wendy's remains a staple in the fast-food industry with over 6,700 locations worldwide.
