Toy blocks are the building blocks of success at LEGO. Keeping little hands busy worldwide for decades, LEGO Holding (dba LEGO Group) has made more than 480 billion of its interlocking toys. In a nod to kids' growing high-tech skills, the toymaker offers LEGO Mindstorms to build PC-programmable robots and BIONICLE sets that feature an evolving online story line. Other collections include LEGO Space Police and LEGO City. It makes its Star Wars and Indiana Jones toys under license with Lucasfilm. The group owns namesake retail outlets in the US and Europe and sells its products in more than 130 countries. Vice chairman Kjeld Kirk Kristiansen, grandson of the founder, is LEGO's majority shareholder (Source: Hoovers Company Profile).
