I've actually been extremely impressed with Lego's business management.
They are the best and most popular toy company in the world. They have extremely high quality, wide spanning audiences, backwards compatability of nearly a century, and they've even shown resilience in learning from their 90's mistakes.
Their product appeals to model builders, collectors, architects, engineers, artists... and not to mention kids! Truly an amazing hobby. It's even educational - teaching manual dexterity, how to follow instructions, and engineering basics. They even have very successful video games and kids shows! Whatever they do, they seem to do well (customer service too!).
I'd actually argue it's never been a better time to be a fan of Lego - just look at some of the beautiful, well-engineered sets they're coming out with. Lego has a way of appealing to every niche.
