The toys were originally designed in the 1940s in Europe and have achieved an international appeal, with an extensive subculture that supports Lego movies, games, video games, competitions, and four Lego themed amusement parks.
The Lego Group began in the workshop of Ole Kirk Christiansen, a carpenter from Billund, Denmark, who began making wooden toys in 1932. In 1934 his company came to be called Lego. It expanded to producing plastic toys in 1940. In 1949 Lego began producing the now famous interlocking bricks, calling them "Automatic Binding Bricks". These bricks were based largely on the design of Kiddicraft Self-Locking Bricks, which were released in the United Kingdom in 1947. Lego modified the design of the Kiddicraft brick after examining a sample given to it by the British supplier of an injection-moulding machine that the company had purchased. The bricks, manufactured from cellulose acetate, were a development of traditional stackable wooden blocks that locked together by means of several round studs on top and a hollow rectangular bottom. The blocks snapped together, but not so tightly that they required extraordinary effort to be separated.
The company name Lego was coined by Christiansen from the Danish phrase leg godt, which means "play well". The name could also be interpreted as "I put together" and "I assemble" in Latin, though this would be a somewhat forced application of the general sense "I collect; I gather; I learn"; the word is most used in the derived sense "I read".
The Lego Group's motto is kun det bedste er godt nok which means 'only the best is good enough'. This motto was created by Ole Kirk to encourage his employees never to skimp on quality, a value he believed in strongly. The motto is still used within the company today.
