The Lego Group 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. On 11 August 2017, Lego announced that Niels B. Christiansen would become the new CEO, effective 1 October of the same year. The history of Lego spans nearly 100 years, beginning with the creation of small wooden playthings during the early 20th century. Manufacturing of plastic Lego bricks began in Denmark in 1947, but since has grown to include factories throughout the world. In 1961, Lego was managed by Samsonite until 1972 in the United States and 1986 in Canada.
The Lego Group seized by Finland customs authorities. The packaging of the Enlighten products was similar to official Lego packaging. Their Chinese manufacturer failed to appear in court, and thus Lego won a default action ordering the destruction of the shipment. Lego Group footed the bill for the disposal of the 54,000 sets, citing a desire to avoid brand confusion and protect consumers from potentially inferior products. In 2004, Best-Lock Construction Toys defeated a patent challenge from Lego in the Oberlandesgericht, Hamburg. The Lego Group has attempted to trademark the "Lego Indicia", the studded appearance of the Lego brick, hoping to stop production
