The Whopper sandwich, Burger King's signature product. When the predecessor of Burger King first opened in Jacksonville in 1953, its menu consisted predominantly of basic hamburgers, French fries, soft drinks, milkshakes and desserts. After being acquired by its Miami, Florida, franchisees and renamed to its current moniker in 1954, BK began expanding the breadth of its menu by adding the Whopper sandwich in 1957. This quarter-pound hamburger was created by Burger King's new owners James McLamore and David Edgerton as a way to differentiate BK from other burger outlets at the time. Since its inception, the Whopper has become synonymous with Burger King, and has become the focus of much of its advertising. The company even named its new kiosk-style restaurants Whopper Bars.
As the company expanded both inside and outside the US, it introduced localized versions of its products that conform to regional tastes and cultural or religious beliefs. International variations add ingredients such as teriyaki or beetroot and fried egg to the Whopper; beer in Germany, Italy and Spain; and halal or kosher products in the Middle East and Israel. To generate additional sales, BK will occasionally introduce limited time offers (LTOs) that are versions of its core products, or new products intended for either long or short term sales. Items such as the Texas Double Whopper and various sandwiches made with mushrooms and Swiss cheese have been rotated in and out of its menu for several years, while products such as its 1993 Meatloaf Specialty Sandwich offering and accompanying limited table service, along with special dinner platters, failed to generate interest and were discontinued.
In order to appeal to as many demographic groups as possible and better compete with its competitor Wendy's, Burger King added a multi-tiered value menu in 1993 with items priced at 99¢, US$1.99 and $2.99. The additions, part of then CEO James Adamson's back to basics program also called Operation Phoenix, were an attempt to add not only a value menu, but also a line of value meals. The tiered menu was replaced with a more standard value menu in 1998, while the value meals were separated into their own menu segment. This value menu featured seven products: Whopper Jr., five-piece Chicken Tenders, a bacon cheeseburger, medium sized French fries, medium soft drink, medium onion rings, and small shake. In 2002 and 2006, BK revamped its value menu, adding and removing several different products such as chili and its Rodeo Cheeseburger. Many of these items have since been discontinued, modified or relegated to a regional menu option. To better appeal to a more adult palate and demographic, BK introduced several new products to its menu in 2003, including several new or revamped chicken products, a new salad line and its BK Joe brand of coffee. Some of the new products, including its Enormous Omelet Sandwich line and the BK Stacker line, brought negative attention due to the large portion size, and amounts of unhealthy fats and trans-fats. Many of these products featured higher quality ingredients like whole chicken breast, Angus beef, and natural cheeses such as cheddar and pepper jack. Again, not all these products, such as the BK Baguette line, have met corporate sales expectations.
With the purchase of the company in 2010, 3G began a program to restructure its menu designed to move away from the male-oriented menu that had dominated under the previous ownership. The first major item to be introduced was a reformulation of its BK Chicken Tenders product in March 2011. Over the next few months, approximately 20 new products were researched and developed while others were reformulated, including its Chef's Choice Burger. Eventually pruned down to 10 items, Burger King began deploying the items in the United States throughout 2011–2012 with the official roll out beginning April 2012. The changes included new ice cream products, smoothies, frappés and chicken strips. The Whopper was the most prominently reformulated product in this round of introductions with a new type of cheese and packaging.
