Rising costs and wartime restrictions on sugar saw the vanilla and strawberry pieces phased out, leaving only the more popular chocolate.

[citation needed] To mark the 75th anniversary of the introduction of the candy bar, Mars introduced 3 Musketeers Mint, the first brand extension, in August 2007.

[8] The candy is made of a whipped nougat mousse formed into very large slabs, which are cut to size and enrobed in milk chocolate.

3 Musketeers was advertised on television on the 1950s-era Howdy Doody show, along with a song that Buffalo Bob Smith encouraged children to sing.

The advertising campaign was developed by Will Vinton Studios, whose previous works include the M&M's characters, The Noid and The California Raisins.

The campaign was developed and directed by the advertising agency Tribal Worldwide, who explained the project as an effort to establish relevancy and recognition among Generation Z.
