The Twix candy bar, first introduced in 1979, was known as a "Raider" bar in France, Germany and several other European countries until 1991 when Mars decided to standardize its name. The change was not well accepted in countries such as Germany where customers mocked the name change as a transparent attempt to sell more candy bars by simply updating the name. The Twix bar consists primarily of a cookie center topped with caramel and coated with milk chocolate.
