Though people often associate anything Mars related as being invented and introduced in America first... Those same people forget that Mars, Inc. has had a long and powerful position in the British market as well. Introduced in 1967 in the United Kingdom, Twix made stayed across the great pond for more than a decade before finally being brought over to the United States in 1979.
The old slogan "Two for me, none for you" resulted in hundreds of deaths as people refused to take that answer. Apparently risking your life was completely worth the price of at least one Twix. Makes me wonder if they used to bestow those who ate them the power of the Highlander.
