In the mid to late 1970s, Jack's was expanding into south Alabama and the Florida panhandle. In the 1980s many of these locations began to close, but at least one individual was having success with Jack's. Benny LaRussa, primarily involved in the grocery business, had purchased a single franchise in the 1960s. In 1979, LaRussa abandoned groceries and purchased a franchise territory of 13 Jack's stores. From then until 1988 he expanded his territory to 33 stores. Then, in 1988, LaRussa purchased the total franchise rights to the Jack's concept. In 2015, Jack's was acquired by a fund managed by Onex Corporation, a private equity company based in Toronto, Canada.
