M&M's - Which Hand Commercial (1954)

Step back to the 1950s and revisit one of the most iconic advertising campaigns in US history: the M&M's "Which Hand" commercial. This simple yet brilliant ad demonstrated the candy's unique selling proposition – that it "melts in your mouth, not in your hand." At a time when chocolate bars were notoriously messy, M&M's offered a clean, convenient alternative. The visual proof shown in the commercial was groundbreaking and instantly memorable, cementing the famous slogan in the public consciousness for generations. It wasn't just an ad; it was a demonstration that defined the product and its role as a mess-free treat, making M&M's a household name and a staple snack.
