What does BRIO stand for?

I’ve been on a mad hunt for BRIO-brand construction toys today. Along the way I found out here what BRIO stands for:

BRIO stands for the Brothers Ivarsson of Osby, the three sons of founder Ivar Bengtsson. Today Osby in southern Sweden remains BRIO’s headquarters, while a large proportion of the production takes place in Osby and Killeberg.

The BRIO website has the weirdest FAQ section I’ve ever seen: most of the questions seem to be missing answers.
