I've been wondering recently when the spelling of the word organization got changed to organisation?
According to the dictionary, and my almost faultless spelling ability, it is organization. But recently I have found it spelled organisation everywhere I see it. I thought maybe it was the British way of spelling it but I checked and found that Americans are misspelling it, too.
It can't be typos because it is too pervasive and consistent, and is found in documents that should have been spell-checked.
