Question: where did jack in the box originate from

title: Jack in the Box
text: The commercials in the `` Jack 's Back '' campaign ( which has won several advertising industry awards ) tend to be lightly humorous and often involve Jack making business decisions about the restaurant chain 's food products , or out in the field getting ideas for new menu items . While a series of ads claiming to ask when Burger King and McDonald 's will change their ways about making their hamburgers featured a phone number , it is unknown whether the caller would actually be connected to Jack himself . In addition , many commercials have advertised free car antenna balls with every meal , thus increasing brand awareness . Often different types of antenna balls were available during a holiday or major event or themed toward a sports team local to the restaurant . The antenna balls have since been discontinued due to the demise of the mast - type car antenna . Popular
