Fanta originated when it became illegal to import Coca-Cola into Nazi Germany during World War II due to a trade embargo.

The name was the result of a brief brainstorming session, which started with Keith exhorting his team to "use their imagination" ("Fantasie" in German), to which one of his salesmen, Joe Knipp, immediately retorted "Fanta!"
