Thanks to backward compatibility, kids could integrate LEGO model buildings from one kit with LEGO model cars, light pylons, traffic signs, train tracks, and more from other kits. No matter what the toy, every brick clicked with every other brick, which meant every LEGO kit was expandable. Thus, the LEGO universe grew with the launch of each new toy.
