Jack in the Box Inc., founded in 1951, is a restaurant company that operates and franchises Jack in the Box® restaurants and, through a wholly owned subsidiary, Qdoba Mexican Grill® in a combined 45 states plus the District of Columbia. Jack in the Box is among the nation's leading fast-food hamburger chains, with more than 2,200 quick-serve restaurants in 19 states. As the first major hamburger chain to develop and expand the concept of drive-thru dining, Jack in the Box has always emphasized on-the-go convenience, with approximately 85 percent of the half-billion guests served annually buying food at the drive-thru or for take-out. In addition to drive-thru windows, most restaurants have indoor dining areas and are open 18-24 hours a day. Jack in the Box pioneered a number of firsts in the quick-serve industry. It was the first major fast-food chain that started as a drive-thru, and it was also the first to introduce menu items that are now staples on most fast-food menu boards, including a breakfast sandwich and portable salad. Today, Jack in the Box offers a broad selection of distinctive, innovative products targeted at the fast-food consumer, including hamburgers, specialty sandwiches, salads and real ice cream shakes. Hamburgers represent the core of the menu, including the signature Jumbo Jack®, Sourdough Jack®, Ultimate Cheeseburger and the 100% Sirloin Burger. And, because value is important to fast-food customers, the company also offers value-priced products on “Jack's Value Menu,” including tacos, a chicken sandwich and the Breakfast Jack®.
