The redundant apostrophe (e.g. apple's 70p per pound, hence "the greengrocer's apostrophe) may be growing usage, and be becoming acceptable, but it began as a manifestation of striving ignorance. Someone mistakenly thought the above ex. required a ' when it didn't, and it became popular among the same ignorant group.

It may be US usage; to me , CD's, the 1970's, etc. simply looks like usage by those who never fully grasped grammar; like I never fully grasped science. Doensn't mean to say we science-ignorant people can waffle on any old popular how.

Popularity doesn't make it correct. Except in language. Of course. Harumph.
