Many people think that the 3 Musketeers bar got the wrong name when it was packaged incorrectly prior to its released. Snopes reports that the myth explains why the 3 Musketeers is so confusingly named.
Rumor has it that the Milky Way, which has three ingredients, was supposed to be labeled with the name 3 Musketeers. The labels were mistakenly switched, but Mars Inc. couldn’t correct the error after both candies became so popular.
According to Leaf, the 3 Musketeers actually got its moniker from the fact that it initially contained three separate bars in one wrapper. Each had a different nougat flavor, including vanilla, chocolate and strawberry. When it was launched in 1932, the candy cost $.05.
Even though buying one bar gave you a variety of options, the chocolate nougat was the most popular. During World War II, the government rationed sugar, and production of the 3 Musketeers became too expensive to offer every flavor.
Strawberry and vanilla were discontinued, and the bar maintained its chocolate nougat center. Other limited-edition flavors have been rolled out over the years, including mocha cappuccino, orange, mint and raspberry.
What makes the saga even more confusing is that outside of the U.S. and Canada, Mars sells a bar called the Milky Way, which is just like the American 3 Musketeers. The candy that Americans call the Milky Way is called a Mars bar everywhere else.
