Gizmodo: Lego Brick Timeline: 50 years of Building Frenzies and Curiosities – The LEGO brick turns 50 at exactly 1:58 p.m. today, January 28, 2008…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.
