KFC and McDonalds are the most famous fast-food restaurants all over the world in which every person had eaten at least once. But it is doubtful whether anyone has ever thought about what makes them go to eat there. Probably, it is the logo that influence people.

It is not the advertising, but logo that helps mostly to recognize the fast food chain. Kentucky Fried Chicken was established by Colonel Harland Sanders in 1952. It is him who one can see on the logo already for 50 years. There were five changes of the KFC’s logo during half of the decade. The last logo that was appeared in year 2006 can be voted as the best among previous four.
