Through its long history, Lego has enjoyed a wide range of production features. Lego has been able to create some of the most loved toys around the world thanks to these features. This includes the development of a unique interlocking mechanism and the use of plastic in place of other materials. These unique features helped the company become the largest toy manufacturer in the world.
The 1960s saw the company continue to expand rapidly. One major change occurred when Godtfred Kirk’s cousin, Dagny Holm, joined the company as a modelbuilder. Dagny had a knack for creating large-scale models and worlds which were displayed in the showroom. This was a great way to showcase the potential of LEGO bricks, and to generate interest amongst children.
In 1971, the LEGO system expanded into new territories with the additions of dollhouses and furniture. In 1972, the program was further expanded by the additions of ships and boats sets, which included floating hull pieces. In the 1960s, the company began its international expansion by selling its products in North America via a licensing arrangement with Samsonite.
In the 1980s, the company continued to grow and diversify its offerings, as well as modernize. The company also established a research and design department that worked to keep the LEGO System at the forefront of innovation. It also saw the introduction of themed sets that allowed users to create specific models without having to figure out what to do on their own. This was a first step towards building more complex models and allowed kids to get a hands-on experience with Legos.
