Keith J. Kramer and his uncle-in-law, Matthew Burns, opened a restaurant in 1953 using the Insta-Broiler to cook many burgers quickly.
McDonald’s is headquartered in Downey, California. Taco Bell and In-N-Out are both in Irvine, California.
After four years, Insta-Burger King introduced their most renowned product, the Whopper, for 37 cents.
The Insta-Broilers worked well for a while, but eventually, the meat drippings would damage the heating element.
The Whopper buns didn't arrive in time for Luis Arenas-Pérez's 1963 Burger King Grand Opening in Carolina, Puerto Rico.
When Burger King first expanded into Australia in 1971, it faced a unique problem: The name had already been trademarked in the country.
McDonald’s used to boast about how many customers they served, but Burger King has a startling number, too.
We should note, however, that saying Burger King runs these stores isn’t totally accurate, as almost 100% of BK locations are owned and operated by independent franchisees.
