After the US entered the war in 1941 Max Keith couldn't get Coca Cola syrup from America to make Coke, Keith invented a new drink out of the ingredients he had available to him and made it specifically for the Nazi market and the Third Reich. The drink was called Fanta. In 1943 alone he sold 3 million cases of Fanta in the Nazi empire.
