I'm trying to think of some examples. At present, I can think of two: the phrase "buck naked" was misheard and misrepeated as "butt naked", which has become a new standard. Although it is technically incorrect, it has become so universal that it is becoming a new standard. Similarly, the phrase "hate on" is currently a popular grammatically incorrect usage. If it survives long enough, it might end up becoming normative.
Interestingly enough, incorrect usages can become normative and still continue to be incorrect. The best example of that is "ain't", which persists in the language and persists as an example of incorrect usage at the same time.
On spelling, changes are rarer. One notable example would be the accepted use of "lite" instead of "light".
Political correctness is the pettiest form of casuistry.

Yes, the long "s" is just a variant. It didn't have a name in Old English.

Eh . . . the Ampersand is probably now considered a logogram rather than a ligature.
