Lego

Lego (pronounced LEG-oh; in Danish, [ˈle̝ːko]) is a line of plastic construction toys made by the Lego Group, a private company headquartered in Billund, Denmark. The toys are built from colorful interlocking bricks molded from acrylonitrile butadiene styrene (ABS), plus gears, miniature figurines known as minifigures, and many other components. These pieces can be joined in countless configurations to create things like vehicles, buildings, and even working robots; once assembled, a model can be dismantled and the parts reused for something new. The Lego Group is one of Europe’s largest companies and leads the world in toy sales.

The company got its start in the workshop of Ole Kirk Christiansen, a carpenter from Billund who began crafting wooden toys in 1932. By 1934, his business was named “Lego,” a contraction of the Danish phrase *leg godt*, meaning ‘play well.’ In 1947, Lego started making plastic toys, and two years later it introduced an early version of the interlocking bricks, calling them “Automatic Binding Bricks.” These were inspired by the self-locking bricks invented by English toymaker Hilary Page in 1939, which his company Kiddicraft had patented in the UK in 1940 and displayed at the 1947 Earl’s Court Toy Fair. Lego had received a sample of the Kiddicraft bricks from the supplier of an injection-moulding machine it bought in Windsor, England. Originally made from cellulose acetate, the bricks improved on traditional stackable wooden blocks. In 1981, Lego reached an out-of-court settlement with Page’s estate—reportedly around £45,000—to continue using the brick design; the Kiddicraft trademark was later sold separately to Fisher-Price.

In 1936, Christiansen coined the company motto, “only the best is good enough” (Danish: *det bedste er ikke for godt*, literally “the best isn’t excessively good”), to push his employees toward quality. By 1951, plastic toys made up half of Lego’s output, even though the Danish trade magazine *Legetøjs-Tidende* (“Toy Times”) wrote after visiting the Billund factory in the early 1950s that plastic would never replace wooden toys. Despite that common view, Lego became a notable exception, partly because of Ole Kirk’s high standards.

In 1954, Christiansen’s son Godtfred became the junior managing director. A conversation with an overseas buyer sparked the idea of a toy system. Godtfred saw that Lego bricks could form a creative play system, but they still had technical issues: their locking ability was limited, and they weren’t versatile enough. The modern brick design was developed in 1958, and ABS replaced cellulose acetate as the material five years later. A patent for the modern brick was filed in Denmark on 28 January 1958, and in other countries over the following years.

The Duplo line, introduced in 1969, offered blocks twice the length, width, and height of standard Lego bricks, aimed at younger children. In 1978, Lego produced the first minifigures, which became a staple in most sets. In 1997, a wave hit a cargo ship off Cornwall, England, sweeping over five million Lego pieces into the sea; they have washed ashore for decades, drawing media and social media attention. In May 2011, Space Shuttle Endeavour mission STS-134 carried 13 Lego kits to the International Space Station as part of the Lego Bricks in Space program, where astronauts built models to observe their behavior in microgravity. In May 2013, the largest model ever—a life-size Star Wars X-wing fighter made from over five million bricks—was displayed in New York City. Other record-breaking builds include a 34-meter tower and a 4-kilometer railway. In February 2015, Brand Finance ranked Lego the “world’s most powerful brand,” surpassing Ferrari.

Though Lego has long been seen as a children’s toy, adult fans have also existed. In 2020, Lego introduced sets for ages 18+, often more expensive and complex models based on real or fictional objects, like the Concorde or Rivendell. Their release timing aligned with the COVID-19 pandemic, as many adults bought them to build during lockdowns. Popularity among adults grew further with *The Lego Movie* and the reality series *Lego Masters*. By 2024, nearly 15% of sets released in the U.S. targeted adult builders. In May 2025, Lego announced plans to move its London headquarters from Farringdon to 76 South Bank.
