In 1978, Donald N. Smith was hired from McDonald's to help restructure the corporate operations of Burger King to better compete against his former company as well as the then up-and-coming chain, Wendy's. As part of an operational overhaul he dubbed "Operation Phoenix", one of his first changes to the company's menu was to add the Burger King specialty sandwich line in 1979. This line—with many non-hamburger sandwiches, including chicken and fish—significantly expanded the breadth of the BK menu. It was one of the first attempts by a major fast food chain to target a specific demographic, in this case adults aged between 18 and 34 years, members of which were presumably willing to spend more on a higher quality product. The new products were successful, and the company's sales increased by 15 percent. While most of the line has since been discontinued, the company's Original Chicken Sandwich is still offered in all of its global markets, and the ham and cheese sandwich is a regional offering.
