The company was founded in 1932, by Ole Kirk Christiansen. The name Lego is derived from the Danish phrase leg godt, meaning "play well". In the first half of 2015, The Lego Group became the world's largest toy company by revenue, with sales amounting to US$2.1 billion, surpassing Mattel, which had US$1.9 billion in sales.

The basic LEGO brick has remained unchanged since its patent, and this enduring design has been associated with the toy’s widespread popularity. These bricks have become a recognizable part of childhood in many parts of the world. The LEGO Group, which has remained family-owned by the Christiansen family, was among the first inductees to the U.S. National Toy Hall of Fame in 1998. Additionally, it was recognized as “Toy of the Century” by several organizations in 2000.
