i recently heard that when the milky way and three musketeers candy bars were introduced (at the same time), mars somehow mixed up the wrappers, which explains why the candy bar with three main ingredients is called ‘milky way’ and the milky candy bar is called ‘three musketeers.’ apparently they’ve since fixed the ingredient labels but never corrected the original mistake.
I heard that the origin of “Three Musketeers” was that the original candy bars had two indentations in the middle, so you could easily break it apart and share with a couple of friends. There could be some truth to a mixup of names, too, though.
Nah. Here’s the original basis for the name “Three Musketeers”, according to Candy USA:
1933 M&M Mars debuts the 3 Musketeers Bar, originally made as a three-flavor bar featuring chocolate, vanilla and strawberry nougat. In 1945, it was changed to all chocolate nougat.
Bibliophage, a Milky Way and a Milky Bar in Britain are different. A Milky Way is the choclolate coated, whipped “fondant”-like bar, whereas a Milky Bar is a thin white chocolate bar.
I’d also heard that story you mention regarding the US/UK differences - a family split across the countries.
