When the company first began, its menu consisted predominantly of hamburgers, french fries, soft drinks, and desserts. Beginning with the the Whopper sandwich in 1957, BK has expanded the breadth of its menu by adding various non-beef items like chicken, fish and vegetarian offerings such as salads and meatless sandwiches; a breakfast menu; and non-soft drink beverages such as Icees, juices and bottled waters. Additionally, 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. To generate additional sales, BK will occasionally introduce limited time offers (LTO) of special versions of its products or bring out completely new products intended for either long or short term sales. Not all of these products and services have been successful, in 1993 Burger King introduced limited table service and special dinner platters; the concept failed to generate interest and was discontinued.As with other fast food companies, BK has recently begun introducing products that feature higher quality ingredients like whole chicken breast, natural cheeses such as cheddar and pepper jack, and other menu fair that attempts to appeal to the more adult palate and demographic. Again, not all of these products have met corporate sales expectations.
