I was just reading a story on AOL (actually a kind of boring story) about how companies got their names. One of the companies they talked about was HASBRO, which according to the article was named Hassenfeld Brothers until they adopted the name Hasbro in 1968.
Now I could swear (and often do) that there were Hasbro toys when I was kid. However if this story is correct, there was no Hasbro until I turned 18.
Granted, this is not one of the great mysteries of the 20th or 21st century, but I do find it strange.
