Burger King Corporation (BK, stylized in all caps) is an American multinational chain of hamburger fast food restaurants. Headquartered in Miami-Dade County, Florida, the company was founded in 1953 as Insta-Burger King, a Jacksonville, Florida–based restaurant chain. After Insta-Burger King ran into financial difficulties, its two Miami-based franchisees David Edgerton (1927–2018) and James McLamore (1926–1996) purchased the company in 1959 and renamed it "Burger King".[5] Over the next half-century, the company changed hands four times and its third set of owners, a partnership of TPG Capital, Bain Capital, and Goldman Sachs Capital Partners, took it public in 2002.
