The Open Championship

[whatwhatwhat]

I can't answer when it became fashionable to call it the British Open, because that was many years before I was born. If you don't recall North Americans referring to The Open Championship virtually exclusively as "The British Open", and the US Open as "the Open", then you're either very young or not from North America. Or both.

I know americans call it the british open is listed like that on the uspga website, as for the rest fair enough, and jamo the name of the "the open" doesnt need to be differentiated from other opens because they arent called the open, they are called the us open or the Irish open etc, they will only be mistaken if you mistake the name of other opens ie calling the us open "the open" and therefore two wrongs shouldnt make a right

The U.S. Open was once often called the National Open. Does anyone know when this moniker faded into disuse? Late 50s or early 60s, I would guess.
