The LEGO brick turns 50 at exactly 1:58 p.m. today, January 28, 2008. This timeline shows these 50 years of building frenzy by happy kids and kids-at-heart, all the milestones from the LEGOLAND themed sets to TECHNIC and MINDSTORMS NXT, as well as all kinds of weird curiosities about the most famous stud-and-tube couple system in the world. Jump to zoom in and tell us what was your first LEGO in the comments.

It all first started in 1947, when LEGO bought their first plastic injection machine. The brick was not invented then but took final form in 1958, when the shape of the stud-and-tube brick was patented. Since then, LEGO sets have been going through dozens of iterations, from the younger version, DUPLO, to the most sophisticated LEGO TECHNIC and LEGO MINDSTORMS NXT sets, going through all the different themes of LEGOLAND and, of course, the most successful line of all times according to LEGO, LEGO Star Wars.
