Godtfred Kirk Christiansen filed a patent for little plastic bricks on January 28, 1958. Fifty years later, 400 billion Lego elements have been produced.
Lego always meant to unlock the imagination of its users. The company emphasizes free-form play and has become wildly popular with children through the years. The Lego Group is the world’s fifth-largest toymaker in terms of sales.
The Lego brick hasn’t changed in the last half-century either. Bricks used today can interlock with those built in 1958.
