Take a moment to look around the room you’re in right now. Look at the device you’re reading this on, the clothes you’re wearing, the snack you’re picking at and the beverage you’re drinking.
It’s not unlikely that all of these things began their life in a country far away from where you live, changing hands dozens of times and travelling thousands of miles before they made it into your home.
We don’t think about it often, but the products we use every day form a map of the world. In 2026, it’s normal to have a device designed in the US, assembled in India, with chips manufactured in Taiwan and camera sensors made in Japan, using lithium from Chile and cobalt from the DRC.
None of this would be remotely possible if it weren’t for one fairly unglamorous idea, formed by a lorry driver watching dock workers struggle with cotton bales at the tail end of the Great Depression.
This is the story of how one entrepreneur, recognising a gap in the market, kick-started a chain reaction that would eventually create the global retail marketplace we have today.
Like with a lot of great stories, the person who revolutionised international retail came from humble origins.
Malcom McLean was born in 1913 in Maxton, North Carolina, the son of a farmer and mail carrier. The family often struggled to make ends meet, and didn’t have enough money to send Malcom to college after he finished high school.
Maxton wasn’t exactly brimming with opportunity, but that didn’t stifle a young McClean’s entrepreneurial spirit. In 1934, still just 20 or 21, he purchased a used truck and began using it to haul tobacco barrels and agricultural produce around North Carolina, eventually founding the McClean Trucking Company with his brother Jim and sister Clara.
The business flourished. Between this opportune purchase and the mid-1940s, McLean Trucking would grow from one truck to 160, well on its way to being one of the biggest carriers in the southeastern US. It was during this period that McClean had a moment of inspiration that would eventually reshape the world’s economy.
In 1937, Malcom was delivering a shipment of cotton to a port in New Jersey. He had to sit and wait for hours, watching longshoremen take individual crates and bales off his truck, pack them into slings, and hoist them piece-by-piece into the ship’s hold.
This was “break bulk” loading, a process that had barely changed for centuries. Cargo was transported to a ship, loaded onto the ship one unit at a time, and then the whole painstaking process was done in reverse at the destination port. Aside from being a huge time sink, this method increased the risk of damage and theft, which merchants treated as just another part of doing business.
Right there on the dock, McClean began to imagine a more efficient solution.
Malcom’s idea would take almost 20 years and a calculated leap into the unknown to realise.
In 1955, he sold his share in the trucking company he’d founded with his siblings, and used the proceeds to buy a struggling tanker operator, the Pan-Atlantic Steamship Company, which he renamed Sea-Land.
Working with engineer Keith Tantlinger, he designed a steel container: 8 feet wide, 8 feet high, and 35 feet long, as well as a unique twist-lock mechanism that could be used to secure it to the deck of a ship. In time, this invention would become the modern intermodal shipping container that’s recognizable all over the world today.
At this very moment, there are somewhere between 20 and 30 million of McClean’s intermodal shipping containers in transit around the world. That’s enough containers to comfortably cover the land area of a city the size of Madrid.
Two key things helped the concept go mainstream:
First, the economic benefits of containerisation were staggering. In the mid-1950s, loading a cargo ship using the traditional break bulk method cost around $5.86 per ton in labour. With McClean’s containers, that figure dropped 16 cents per ton, more than 35 times cheaper. The very first voyage using McClean’s containers, on a converted WWII tanker called the Ideal X, proved that a full cargo ship could be loaded in a matter of hours, rather than days.
Second, rather than guard his patents and secure an advantage for Sea-Land, McClean decided to make his corner-casting and twist-lock designs available royalty-free to the International Organization for Standardization. The ISO’s committee loved the container, and soon used it to establish universal dimensions, corner fittings, and stacking rules which are still in force today.
This universal adoption was another major step in making global trade frictionless. Suddenly, a container loaded by a factory in Osaka could be lifted by crane in Rotterdam, strapped to a train, and delivered to a warehouse in Lisbon, all without anyone having to touch the products inside.
Once the world had agreed on a single container, the way was cleared for another transformation; not in terms of shipping, but where things were made.
In his book The Box, economist Marc Levinson explains how containerisation didn’t just make trade cheaper, but also geographically indifferent. With McClean’s containers making ocean freight cheaper and more reliable, a factory’s distance from the end customer stopped mattering nearly as much as distance from cheap labour and materials.
For years, high shipping costs had offered a certain level of protection to domestic producers, but those days were over. Now, a factory in Malaysia could have a finished shirt displayed in a shop in New York more cheaply than a domestic manufacturer based in the city’s own garment district.
In the last quarter of the 20th century, the consumer-facing effects of this change were jaw-dropping. The United States imported four times as many distinct varieties of goods in 2002 as it had in 1972, generating a huge consumer benefit in terms of both choice and price.
For the first time in history, a normal household could furnish their home, dress a family, and stock a kitchen with goods sourced from dozens of different nations, thanks to newly-lowered price points untouched by the immense distances the products had travelled.
Several retail businesses that developed during this period showed just how much these new supply chains reshaped the customer experience:
IKEA: Founded in 1943, IKEA stumbled onto perhaps the most container-friendly example of product design almost by accident. In 1956, the same year that the Ideal X had her maiden voyage, designer Gillis Lundgren removed the legs on a table to fit it more easily into his car, and noted that the disassembled item took up just a fraction of the space. IKEA built its entire business model around this insight, with products designed from the outset to minimise space requirements and ship as efficiently as possible. Today, IKEA sources from more than 2,100 suppliers across 54 countries, and is still known for both low prices and quality - a model that’s only possible thanks to the efficiency of standardised containerisation.
Walmart: Sam Walton founded what’s now America’s biggest retailer in 1962. The first two decades were spent as a relentlessly efficient discount retailer, albeit with local supply chains. This model began to change in the 1980s, when the company established an overseas purchasing office in Hong Kong. In 1991, Walmart set up the revolutionary Retail Link system, its own real-time data platform that sent POS information directly to suppliers around the world. This meant that container-loads of merchandise could be timed to arrive exactly when shelves needed restocking. By embracing a sourcing model based around the efficiency of containerisation, and new innovations in operational data sharing, Walmart was able to build an highly efficient model that consistently beat its competition on price and product variety.
Zara: The flagship brand of Spanish multinational Inditex, Zara took a slightly different approach to developing a modern supply chain, though one that’s equally dependent on containerisation. Since its founding, Zara has focused on speed as a competitive advantage. When it first started in 1975, rival fashion brands typically needed 4-8 weeks to get a garment from its design phase to the shop floor. Zara was able to compress this into just two weeks through tight vertical integration, manufacturing many of its garments close to its headquarters and shipping new stock to stores twice a week through a huge automated distribution hub in Arteixo. This focus on efficiency meant they could refresh their range almost constantly while keeping operating costs to a minimum.
By the 1990s, the architecture of retail had changed completely. McClean’s innovative steel box had solved one of the biggest issues in global commerce, and unlocked a new way of getting products across continents quickly, cheaply, and reliably.
What it hadn’t made was a direct channel to the end customer’s home. Fortunately, this was right around the corner.
As millions of households got internet access in the 90s, a new generation of entrepreneurs saw an opportunity waiting to be tapped. The internet, still considered a novelty at the time, offered the potential for retailers to break down many of the limitations set by mail-order catalogues.
No more flipping through countless pages, just type what you’re looking for into this nifty thing called a search bar. No more worrying about printing and postage costs to share a large selection of products with your audience - the space on a website was practically infinite. Customers getting annoyed at the time it takes to find out if a product’s in stock? Ecommerce lets you display a live, accurate stock level on each product page.
Ecommerce matured rapidly, not least of all thanks to Amazon. Jeff Bezos didn’t invent ecommerce, but it’s easy to argue that he took its inherent benefits and perfected them.
In the early days of ecommerce, buying anything online was seen as risky, and Amazon invested heavily in secure payment portals, reliable fulfillment, and clear returns policies. These features, combined with a commitment to low prices, helped positive experiences compound, forming the start of the now-famous “Amazon Flywheel”. By building a great customer experience, Amazon made itself more accessible to a whole swathe of consumers who had been suspicious of this scary new thing called “online shopping”.
Beyond the shopping experience, Amazon was quick to develop their delivery logistics, distinguishing themselves as a company that not only made online shopping safe and practical, but fast.
This was achieved in a chain of developments through Amazon’s early history, aimed at giving their logistics an edge over slower ecommerce brands:
1997 - 1999 - Expansion Beyond Seattle: Following its 1997 IPO, Amazon began to develop their fulfillment infrastructure outside of the Seattle area, investing for long-term efficiency rather than short-term profits. With new fulfillment facilities springing up around the US, the company was able to improve both their storage capacity and their geographic reach.
2005 - Amazon Prime Launches: With fulfillment apparatus now spread across the country, Amazon was able to launch the first iteration of Amazon Prime. For an annual fee, customers could receive unlimited two-day shipping on eligible products, making super fast shipping the default experience for millions of customers.
2006 - 2008 - FBA and Continued Expansion: FBA allowed third-party sellers to store their products in highly systematised fulfillment centres, making many more products eligible for Prime shipping. Amazon also continued opening more fulfillment centres, further reducing the distance between the product and the end customer.
2009 - Launch of Local Express Delivery (Same-Day Delivery): Amazon introduced its first same-day delivery service, bringing what had been an exclusive luxury to ordinary ecommerce shoppers.
These innovations not only helped to establish Amazon as a leader in the emerging ecommerce sector, but set new standards that shoppers quickly came to expect from other stores.
Global retail has gone through some revolutionary changes over the past century. Even with his innovative, forward-thinking mindset, it’s unlikely that Malcom McClean could have imagined the massive access to products that the average consumer has today when he first sat in the cab of his truck and came up with his big idea.
McClean didn’t set out to make the world a much smaller place when he first sketched out his shipping container, innovation has a strange way of taking on a life of its own, creating whole new markets and practices that change the very definition of the word ‘retail’.
By creating a popular solution to one specific problem, McClean tipped the first domino that led to a rapid transformation of global supply chains, opening up channels for materials and products to cross borders faster than ever before. With these mature logistics in place, ecommerce pioneers could develop highly automated fulfillment networks, so that now a product that was once considered exotic or luxurious can be delivered to your door 24 hours after you tap a button on your phone.
With AI tools’ growing accessibility and agentic retail beginning to take shape, there’s no telling how the next small domino-tip could reshape ecommerce and logistics in the future.
