In 1950 a man named Robert O'Petersen built the first Jack-In-The-Box restaurant at El Cahon and 63rd streets in San Diego. The restaurant was origanally built for drive-thru and walk-up service only-customers would speak into a clown's mouth to order their food. The clown was blasted to smithereens with explosives in a 1980 advertising campaign, however, signifying a shift toward a more diverse adult menu.

The Jumbo Jack hamburger has been on the menu since 1974.
