The piece of gum you casually unwrap today represents thousands of years of human history. From ancient civilisations chewing tree resins for pleasure and health, through the industrial revolution that created the modern gum industry, to today's high-tech formulations designed for dental health and cognitive benefits—chewing gum has been on a remarkable journey.
In this article, we'll trace the fascinating evolution of chewing gum, exploring how a simple human instinct to chew became a multi-billion dollar global industry. Along the way, we'll meet the inventors, entrepreneurs, and innovators who shaped the gum we know today.
Ancient Origins: The First Gum Chewers
Humans have been chewing gum-like substances for at least 9,000 years—long before recorded history. Archaeological evidence reveals that prehistoric people chewed birch bark tar, possibly for medicinal purposes or simple enjoyment. The practice seems almost instinctive, emerging independently across multiple ancient cultures worldwide.
Greece and the Mediterranean
Ancient Greeks chewed mastiche (or mastic), a resin obtained from the mastic tree native to Greece and Turkey. The word "masticate," meaning to chew, derives from this practice. Greeks believed mastic had health benefits and used it to freshen breath and maintain oral health. Mastic chewing spread throughout the ancient Mediterranean world and continues today—Greek mastic gum is still produced and valued for its unique flavour and purported health properties.
The Americas: Chicle Culture
Perhaps no culture embraced chewing gum more thoroughly than the ancient Mayans and Aztecs of Central America. They harvested chicle, a natural latex from the sapodilla tree, and chewed it for enjoyment, thirst relief, and hunger suppression. The word "chicle" would eventually become synonymous with chewing gum in many languages.
Chicle had significant cultural importance. It was considered acceptable for children and unmarried women to chew in public, while married women and men were expected to chew privately. The Mayans also used chicle medicinally and in religious ceremonies.
Different cultures chewed whatever natural resins were locally available: birch bark tar in Northern Europe and Scandinavia, spruce resin among Native Americans, mastic in the Mediterranean, and chicle in Central America. All these substances share the key property of being pleasantly chewable without dissolving.
Native American Traditions
Native American peoples of North America had their own gum traditions, primarily chewing the resin of spruce trees. When European settlers arrived, they adopted this practice. Spruce gum would become the basis for the first commercial gum products in the United States.
The Birth of Commercial Chewing Gum
The transformation of gum chewing from a folk practice to a commercial industry began in the mid-19th century in the United States. Several entrepreneurs recognised the potential to manufacture and sell chewing gum at scale.
John B. Curtis: The First Commercial Gum
In 1848, John B. Curtis created the first commercially sold chewing gum in the United States. Working with his father in Bangor, Maine, Curtis produced "State of Maine Pure Spruce Gum" from spruce tree resin. The crude product was cut into strips and sold in local shops.
Curtis later developed paraffin-based gums, which offered more consistent texture than natural resins. His company, Curtis & Son, became the first chewing gum manufacturer in America, though the business eventually faded as superior products emerged.
Thomas Adams and the Chicle Revolution
The modern chewing gum industry truly began with Thomas Adams, a New York inventor who stumbled upon chicle through a remarkable chain of events. In the 1860s, Adams met Antonio LĂłpez de Santa Anna, the exiled former president of Mexico, who was living in New York.
Santa Anna had brought a large quantity of chicle with him, hoping Adams could help vulcanise it as a rubber substitute. After numerous failed experiments to turn chicle into usable rubber, Adams was about to give up when he noticed his son enjoying chewing some of the raw chicle.
Recognising the opportunity, Adams shifted his focus from rubber to gum. In 1871, he patented a machine for manufacturing chicle-based chewing gum and began selling "Adams New York Gum." The product was unflavoured initially, but its superior chewing quality over spruce and paraffin gums made it an instant success.

The Rise of the Gum Giants
The late 19th and early 20th centuries saw chewing gum evolve from a novelty into a major industry, dominated by companies that still exist today.
William Wrigley Jr.: Marketing Genius
No name is more associated with chewing gum than Wrigley. William Wrigley Jr. started selling soap in 1891, offering baking powder as a free incentive. When the baking powder proved more popular than the soap, he switched to selling baking powder with chewing gum as the incentive. Once again, the incentive outshone the product—customers wanted the gum.
Taking the hint, Wrigley pivoted entirely to gum. He introduced Juicy Fruit and Wrigley's Spearmint in 1893. Through aggressive advertising and innovative marketing—including sending free samples to every person listed in US phone books—Wrigley built the most successful chewing gum empire in history. The company's marketing prowess made gum a household staple rather than an occasional treat.
Bubble Gum: A New Category
In 1928, Walter Diemer, an accountant at the Fleer Chewing Gum Company, accidentally invented bubble gum while experimenting with new gum recipes. His creation, originally called "Dubble Bubble," was less sticky than previous attempts and could be blown into bubbles without breaking as easily.
Bubble gum's pink colour was chosen simply because it was the only food colouring Diemer had available. The colour became iconic, and pink has been associated with bubble gum ever since. Bubble gum opened an entirely new category of gum aimed primarily at children, emphasising fun over freshness.
Modern Innovations
The mid-to-late 20th century brought significant changes to chewing gum, driven by health consciousness, technological advancement, and changing consumer preferences.
The Shift to Synthetic Bases
During World War II, chicle supplies from Central America became unreliable. Gum manufacturers, needing to maintain production, developed synthetic gum bases from petroleum-derived polymers. After the war, these synthetic bases proved cheaper and more consistent than natural chicle, and they gradually replaced it in most commercial gum.
Today, the vast majority of mainstream gum uses synthetic bases, though natural chicle gum has seen a resurgence among eco-conscious consumers.
Sugar-Free Revolution
The introduction of sugar-free gum in the 1950s and 1960s marked a turning point for the industry. Initially marketed for diabetics and dieters, sugar-free gum gained mainstream appeal as the link between sugar and tooth decay became widely understood.
The development of sugar alcohols like xylitol and sorbitol allowed gum to be not just sugar-free but actively beneficial for dental health. Today, sugar-free gum dominates the market in most developed countries, with dental organisations actively recommending it.
Functional Gum
Recent decades have seen gum evolve beyond candy into a delivery system for various functional ingredients. Nicotine gum helps smokers quit. Caffeine gum provides energy boosts. Vitamin-fortified gums aim to supplement nutrition. Gum has become a platform for innovation, with new functional varieties regularly entering the market.
The gum industry continues to evolve. Current trends include sustainable packaging, biodegradable natural bases, and increasingly sophisticated flavour delivery systems. Some researchers are even exploring gum as a delivery method for medications and supplements.
Gum in Australia
Chewing gum has a distinct history in Australia, arriving with European settlement but truly flourishing in the 20th century.
American servicemen stationed in Australia during World War II helped popularise gum culture, sharing their chewing habits with Australians. After the war, major American gum brands expanded into the Australian market, and local manufacturing eventually followed.
Today, Australia has a vibrant gum market with both international brands and locally-focused products. Australian consumers have embraced sugar-free gum particularly enthusiastically, with sugar-free varieties representing an even larger market share than in many other countries.
Cultural Impact
Beyond its commercial success, chewing gum has woven itself into popular culture. From Wrigley Field (named after the gum magnate who owned the Chicago Cubs) to countless movies featuring gum-chewing characters, the simple act of chewing has become a cultural touchstone.
Gum has been associated with rebellion (the rule-breaking student), relaxation (the casual baseball player), and sophistication (the elegantly popping bubbles of vintage advertisements). Its cultural meaning continues to evolve with each generation.
Conclusion
From ancient tree resins to high-tech formulations, chewing gum has been on an extraordinary journey. What began as an instinctive human behaviour—the urge to chew for pleasure and comfort—evolved through industrial innovation into a global phenomenon worth billions of dollars annually.
The next time you unwrap a piece of gum, you're participating in a tradition that spans millennia and connects you to ancient Greeks chewing mastic, Mayan farmers harvesting chicle, American inventors experimenting in their workshops, and generations of chewers around the world. That simple piece of gum carries quite a history in its flavourful folds.
