Lego bricks colorful

Colorful Lego bricks are more than toys: icons of design, engineering, and pop culture for over 60 years.

About this subject

The history of Lego began in 1932 in Denmark, when Ole Kirk Christiansen founded a carpentry workshop. The name Lego comes from the Danish phrase "leg godt," meaning "play well." The interlocking brick system was patented in 1958, allowing pieces from different decades to still fit together perfectly. It is estimated that there are over 400 billion Lego pieces in the world, equivalent to about 60 pieces for every person on the planet.

The manufacturing process is surprisingly precise. Injection molds have tolerances of up to 5 micrometers (0.005 mm), ensuring each brick connects firmly but can be easily separated. Colors follow strict standards: Lego uses its own color numbering system with over 70 active shades. The most common color is bright red, followed by blue and yellow.

Beyond entertainment, Lego bricks have educational and artistic applications. Schools use kits to teach STEM (science, technology, engineering, and mathematics) concepts. Artists like Nathan Sawaya create life-size sculptures using thousands of pieces. Lego also has themed lines reflecting pop culture, such as Star Wars, Harry Potter, and Minecraft, which drive collecting and resale.

Regarding sustainability, Lego announced in 2021 it would begin producing pieces from plant-based plastic derived from sugarcane, although most are still made of ABS (acrylonitrile butadiene styrene). The company also invests in projects to recover pieces lost in the ocean, such as "Lost at Sea," which tracks bricks fallen from ships. In 2024, Lego announced it is testing bricks made from recycled PET bottles, but the durability challenge persists.
