Last month, for the first time in its 82-year history, the Lego Group stacked up as the world's number one toymaker, surpassing Mattel and Hasbro in profits.

The ranking points to the cultural status Lego has achieved in recent years. Much more than a toy, the interlocking blocks have become an icon of open-ended play, great design, and STEM (science, technology, engineering, and math) learning benefits, touted as much in the world of architecture as by children. It's gotten there through consistent innovation (and licensing deals) on what remains basically a single product: The hard, plastic brick.
