M&Ms are colorful, candy-coated chocolate treats that have delighted fans worldwide since their debut in 1941. Packed with history, innovation, and quirky stories, M&Ms offer more than just a sweet snack—there’s a trove of fun facts behind every handful. Here’s a deep dive into what makes M&Ms so unique, from their origins to their pop culture presence, flavor experiments, and more.
The Origins and History of M&Ms
M&Ms were invented by Forrest Mars Sr., son of Mars Company founder Frank C. Mars, in collaboration with Bruce Murrie, son of Hershey executive William Murrie. The partnership gave M&Ms their name: “M” for Mars and “M” for Murrie. The concept was inspired by soldiers eating chocolate pellets with a hard shell during the Spanish Civil War, which prevented the chocolate from melting in their hands. Mars patented the process in 1941, and M&Ms were initially sold exclusively to the U.S. military during World War II. The candies became available to the public in 1947 and rapidly grew in popularity.
How M&Ms Are Made: The Candy Coating Process
M&Ms are made by covering chocolate centers with a thin, crunchy candy shell. The process starts with chocolate, which is shaped into small discs. These are placed in large revolving pans, where they are coated with layers of sugar syrup. Food coloring is added to create the iconic bright shells. Once the coating is complete, the candies are printed with a small “m” on one side—a process that began in 1950 to help distinguish the real M&Ms from imitators.
Colorful Evolution: Changing Colors and What They Mean
The original M&Ms came in five colors: red, yellow, green, brown, and violet. In 1949, violet was replaced with tan. Over the decades, the color lineup has shifted several times:
- In 1976, red M&Ms were temporarily replaced with orange due to concerns about the dye Red No. 2, though it was never used in M&Ms.
- Red returned in 1987 by popular demand, and tan was eventually phased out.
- In 1995, fans voted to add blue as a new permanent color, replacing tan.
Today, standard milk chocolate M&Ms come in red, orange, yellow, green, blue, and brown. Specialty editions sometimes feature unique colors or even custom blends for events and holidays.
Flavor Innovations and Limited Editions
While classic milk chocolate remains the flagship, M&Ms have been released in a variety of flavors and fillings. Some popular and unusual varieties over the years include:
- Peanut (introduced in 1954)
- Peanut Butter
- Almond
- Crispy
- Pretzel
- Caramel
- Mint
- Coffee Nut
- Hazelnut Spread
- White Chocolate
- Seasonal flavors like Pumpkin Spice, Candy Corn, and Hot Cocoa
Limited edition and regional flavors are often introduced for holidays or as promotional tie-ins, making collecting and tasting new M&Ms a fun hobby for enthusiasts.
M&Ms in Pop Culture and Advertising
M&Ms have become pop culture icons, thanks in part to their memorable advertising campaigns. The animated “spokescandies”—including Red, Yellow, Green, Blue, and others—began appearing in commercials in the 1990s and have helped give the brand its playful personality. M&Ms have made appearances in movies, TV shows, and even been featured as special flavors tied to blockbuster film releases.
One of the most famous advertising slogans is “Melts in your mouth, not in your hand,” which first appeared in 1954 and has become synonymous with the brand. M&Ms have also been part of major events, such as being the first candy to travel in space aboard the Space Shuttle Columbia in 1981.

Comparisons: M&Ms vs. Other Candy-Coated Chocolates
M&Ms are often compared to similar treats like Smarties (popular in the UK and Canada), Reese’s Pieces, and Skittles. Here’s how they stack up:
- Smarties: These are also candy-coated chocolates but are flatter and come in pastel colors. The flavor and shell texture differ from M&Ms, and Smarties are made by Nestlé outside the US.
- Reese’s Pieces: These look similar to M&Ms but are filled with peanut butter instead of chocolate. They famously appeared in the movie “E.T.” after M&Ms declined the product placement.
- Skittles: Skittles have a similar size and shape but are fruit-flavored candies with a chewy center, not chocolate.
M&Ms remain unique for their chocolate core and wide array of flavor and color options.
Collecting and Personalizing M&Ms
M&Ms aren’t just for eating—they’re also collectibles. Special edition packaging, seasonal releases, and international varieties have created a market for M&M memorabilia. Mars even operates M&M’s World stores in cities like Las Vegas, Orlando, London, and Shanghai, where fans can create their own blends, buy branded merchandise, and experience interactive exhibits.
For parties, weddings, and corporate events, custom M&Ms can be ordered online with personalized colors, messages, or even images, making them a popular choice for favors and themed decorations.
Common Questions About M&Ms
- What does “M&M” stand for?
“M&M” stands for Mars & Murrie, named after Forrest Mars Sr. and Bruce Murrie, the two business partners who launched the candy in 1941. - Are M&Ms gluten-free?
Plain milk chocolate M&Ms do not contain gluten ingredients, but some varieties (like Pretzel or Crispy) do. Always check the packaging for allergen information, as manufacturing processes can change. - Why are there fewer blue M&Ms in a bag?
The distribution of colors is determined by Mars, and blue is intentionally made less common than some other colors. Each color’s proportion may vary by variety and region. - Can I buy M&Ms in single colors?
Yes, Mars offers bulk purchases of single-color M&Ms and allows customization through their website and at M&M’s World stores for events and parties. - Are M&Ms safe for people with peanut allergies?
Plain milk chocolate M&Ms do not contain peanuts, but cross-contamination is possible in factories that also produce peanut varieties. Always check allergen warnings on the packaging and consult with a medical professional if you have severe allergies. - How long do M&Ms last?
M&Ms are shelf-stable and generally stay fresh for about 12 months if stored in a cool, dry place. Excess heat or humidity can cause the chocolate to bloom (develop a white coating), which affects appearance but not safety.
M&Ms and Food Safety
M&Ms are considered a safe, shelf-stable snack when stored properly. The sugar shell helps protect the chocolate from moisture and temperature swings, although extreme heat can still cause melting or blooming. Because they don’t contain perishable ingredients, M&Ms are less prone to spoilage than some other candies. However, always check expiration dates and inspect for unusual smells or textures before eating older candies.
Alternatives and Dietary Variations
For those with dietary restrictions, several alternatives to standard M&Ms exist:
- Vegan chocolate candies: Some brands offer dairy-free, vegan versions of candy-coated chocolates, though M&Ms themselves contain milk.
- Nut-free chocolate candies: Certain brands specialize in nut-free manufacturing for allergy concerns.
- Sugar-free or reduced sugar candies: While Mars does not currently offer sugar-free M&Ms, other brands make similar treats using sugar substitutes.
Always check labels and manufacturer information to ensure a product meets your dietary needs.
