Where It All Began
The origins of Mars Inc family can be traced to two men: Forrest Mars Sr. and his father-in-law, Frank C. Mars. Forrest, a restless entrepreneur, had already failed at a few ventures before he stumbled upon the Milky Way in England. But it was Frank—already a successful candy maker with a line of products including the Milky Way—who provided the template. The two men clashed over business decisions, leading to a bitter split in 1932. Forrest took the rights to the Milky Way recipe and launched his own company, Mars Inc, in 1933. The first product? The Mars Bar, a chocolate-and-nougat treat that became an instant hit in the U.K. and later the U.S. The early years were about survival. Forrest Mars Sr. was a perfectionist, obsessed with quality control. He insisted on using only the finest cocoa beans and refused to compromise on taste. His approach paid off: by the 1940s, Mars Bars were being sold to U.S. troops during World War II, cementing the brand’s reputation for durability and reliability. But the Mars Inc family’s real breakthrough came in 1941 with the introduction of M&M’s—melting-mouth melts, as the slogan went. The candies were inspired by a British innovation that coated chocolate in a hard sugar shell, making them ideal for soldiers in the field. The partnership with Bruce Murrie, Forrest’s brother-in-law, turned M&M’s into a household name, and by the 1950s, the Mars Inc family was firmly entrenched as a global player.The Early Signs
Even in its infancy, Mars Inc family operated differently. While competitors relied on public listings and investor relations, the Marses kept their company private, ensuring full control over operations. This wasn’t just about money—it was about vision. Forrest Mars Sr. believed that outside interference would dilute the company’s focus on product excellence. His son, John Mars, later echoed this sentiment, insisting that Mars Inc family’s success came from its ability to make long-term decisions without the pressure of stockholder demands. The Mars Inc family’s early years also saw the establishment of a unique corporate culture. Employees were treated like family, with generous benefits and a strong emphasis on loyalty. The company’s slogan, "A Mars a day helps you work, rest, and play," wasn’t just marketing—it was a reflection of Forrest Mars Sr.’s belief that his products should improve people’s lives. This philosophy extended to the workplace, where the Mars Inc family fostered an environment of innovation and secrecy. Even today, the company’s Virginia headquarters remains one of the most secure corporate campuses in the world, with restricted access and stringent confidentiality protocols.The Turning Point
The Mars Inc family’s trajectory shifted in the 1960s and 1970s, as the company expanded beyond chocolate into pet care, Wrigley’s gum, and international markets. The acquisition of Wrigley’s in 1988 was a game-changer, doubling the company’s size overnight and catapulting Mars Inc into the gum market. But the real turning point came with the rise of John Mars, Forrest Sr.’s son, who took over as CEO in 1971. Under his leadership, the Mars Inc family embraced globalization, opening manufacturing plants in countries like Brazil and Indonesia to reduce costs and tap into new markets. What set the Mars Inc family apart wasn’t just expansion—it was their refusal to adapt to every trend. While competitors chased fads like sugar-free or organic products, the Marses stuck to what they knew worked. Their products remained consistent, reliable, and nostalgic. This strategy paid off: today, Mars Inc is the world’s largest snack company, with brands like Snickers, Twix, and Doritos generating billions in revenue. The Mars Inc family’s ability to stay true to its roots while innovating in key areas—like sustainable sourcing—has kept it ahead of the curve."We don’t make decisions based on what’s popular. We make them based on what’s right for the long term." — John Mars, former CEO, Mars Inc
