"wow" was actually an acronym for Wonder Of the World. What is the derivation of "wow"?

Wonder of the World? Ohhhh, I blush! Smugly, I admit, but nevertheless!
Also, Wise Old Woman or you can simply turn it upside down and get MOM. Wait! Wait! that fits Wonder of the World! Which all Moms are, aren't they?
