There are a few other chains that sell fried chicken but they are only in certain parts of the country. Kentucky Fried Chicken is found all over the country because it is the oldest chicken fast food restaurant and it is one of the oldest fast food restaurants to sell any type of food.
That allows it to monopolize fried chicken since it has been around for a long time. On the other hand, Kentucky Fried Chicken is known for having a great recipe for its chicken. It is difficult to improve upon that. Usually, if another fast food restaurant is created, then it tries to find another type of food to sell. It would be in direct competition with KFC.
Colonel Harland Sanders, the entrepreneur who began selling fried chicken from a roadside restaurant, started branding himself as "Colonel Sanders" by popularizing chicken in the fast food industry and diversified the market by providing customers with an option besides the typical hamburger.
The secret recipe is what gives KFC the advantage. IT is a combination of eleven specially selected herbs and spices, which makes the coating on the chicken. KFC is also the second largest restaurant chain in the world. Their slogan is "finger-lickin’ good.” The Colonel created the chain with the concept of serving good, quality southern food, and fast and friendly service.
