Today I went to check spelling for "canceled." I thought it should be "cancelled." Turns out that (according to the internet which is obviously completely factual and correct), "canceled" (one "L") is the preferred American spelling while "cancelled" (2 "L"s) is the British way. And the one "L" achieved it's win in the US as recently as the 1980s. Admittedly, I grew up on the King James version and absorbed British spellings so this may not be such a change for folks who grew up listening to Noah Webster.
For fun you might want to check out the original rules for a game like baseball. Some changes are recent. Others were made long ago. How many swings before a batter strikes "out"? Or what constitutes a "strike"? And where in the world are you supposed to put a question mark when that last word is in quotation marks?
Christmas shopping is another place where the pace of change is obvious. I walked through Best Buy recently. Some of those aisles are filled with items that I don't remember existing 5 years ago. Maybe they did. Maybe it is my memory that's "changed." You tell the story the way you want to tell the story. I'll tell it accurately.
