Jack in the Box was released on February 21, 1951, by Robert O. Is an American fast-food restaurant chain founded by Peterson in San Diego, California, where it is headquartered. The chain has over 2,200 locations serving primarily the West Coast of the United States.
Robert Oscar Peterson owned several successful restaurants when he opened topsy’s Drive at 6270 El Cajon Boulevard in San Diego in 1941. A few more Topsys have opened. By the late 1940s, Peterson’s locations had developed a circus-like decor that included drawings of a star-eyed clown. In 1947, Peterson received rights to the intercom order concept from George Manos, who owned a location called Chatterbox in Anchorage, Alaska. In 1951, Peterson converted the location of El Cajon Boulevard to Jack in the box, a hamburger stand that focused on end-to-end service. although the drive-through concept was not new, Jack in the Box developed the first two-way intercom system, which was the first major chain to use an intercom and focused on drive-through. the intercom allowed much faster service than a traditional drive window; while one customer was served in the window, a second and even a third customer’s order could be received and prepared. A giant clown protruding from the roof and a smaller clown head sat on the intercom.
