Lego, the English name is LEGO, was founded in 1932. The company is located in Denmark. As of 2022, LEGO has a 90-year development history. To trace its origins, we have to start with its golden signature LEGO. The use of the trademark "LEGO" began in 1932. Its word comes from the Danish "LEg GOdt", which means "play well" (play well), and the name quickly became the first high-quality product produced by the LEGO company in the Billund area toy factory. Synonymous with toys. Over the years, the "LEGO" icon has also changed in many forms. The latest icon was produced in 1998. It was slightly adjusted based on the 1973 version to make it easier to spread and identify in the media. The first production site was in a red house in Denmark, where Lego started.
