Lego had received a sample of the Kiddicraft bricks from the supplier of an injection-molding machine that it purchased. These bricks were based on the Kiddicraft Self-Locking Bricks, which had been patented in the United Kingdom in 1939 and released in 1947. In 1949 Lego began producing, among other new products, an early version of the now familiar interlocking bricks, calling them 'Automatic Binding Bricks'. In 1947, Lego expanded to begin producing plastic toys. In 1934, his company came to be called 'Lego', derived from the Danish phrase leg godt, which means 'play well'. The Lego Group began in the workshop of Ole Kirk Christiansen (1891–1958), a carpenter from Billund, Denmark, who began making wooden toys in 1932. Two Lego Duplo bricks with a standard brick for comparison As of July 2015, 600 billion Lego parts had been produced.

Films, games competitions, and eight Legoland amusement parks have been developed under the brand. The Lego Group began manufacturing the interlocking toy bricks in 1949. Anything constructed can be taken apart again, and the pieces reused to make new things. Lego pieces can be assembled and connected in many ways to construct objects, including vehicles, buildings, and working robots. The company's flagship product, Lego, consists of variously colored interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts.

Lego ( / ˈ l ɛ ɡ oʊ/ LEG-oh, Danish: stylized as LEGO) is a line of plastic construction toys that are manufactured by The Lego Group, a privately held company based in Billund, Denmark.
