On January 28th 1958, Godtfred Kirk Christiansen patented the humble Lego brick. His company had existed, making other toys, since 1930—but it was 55 years ago today that the infamous studded plastic brick was officially born.
As the promotional video above—made in the same year—shows, little has changed. (Do watch it: even though it's in German, it's kinda fun, and there's a great section where a Lego designer casually stands on a house to prove the strength of his construction.)
For the most part, Lego is one of the great levelers in the toy world: kids love it, adults get excited about it, and you can build practically anything you like out of it. While most wholesome family fun turns out boring or desperate, Lego transcends age and gender and makes everyone want to play.
