In the Microsoft column, "4" belongs between "3" and "95" (that's NT4; NT5 got renamed "2000"), and "ME" belongs between "98" and "2000".
In the Apple column, "9" belongs between "8" and "X".
Curious omissions. I can sort of understand forgetting "NT4", since that was mainly a server OS and didn't get much attention in the mainstream. And I grant that Windows "ME" is best forgotten. But MacOS 9 was the pinnacle of the original Mac series; my late-90's iMacs ran it for many years.
Ah, well, it's an internet meme, not a Wikipedia page :-) Thanks for posting it!
