Burger King is a global fast-food restaurant chain known for its flame-grilled hamburgers, particularly the iconic Whopper, introduced in 1957. Founded in Miami in 1954 by James McLamore and David Edgerton, the company has become one of the largest hamburger chains, with over 14,000 locations in nearly 100 countries. Burger King distinguishes itself from competitors with its flame-broiled cooking method and the slogan "Have It Your Way," emphasizing customized orders. The company has changed ownership several times, including its acquisition by Pillsbury in 1967 and later by the British company Grand Metropolitan. In 2014, it merged with Tim Hortons, forming Restaurant Brands International, based in Canada. Burger King is the second-largest hamburger chain in the world, competing primarily with McDonald's, and has maintained a strong market presence due to its aggressive marketing and innovative products​.
