Cant read it, but the title literally says “1986, ‘Ms’ joins the Times vocabulary”, so I’m guessing that, you know…1986 is when it became the Times’ standard. This likely corresponds to the campaign of Geraldine Ferraro, which is what I personally remember as the point where the term became widespread.

I don’t understand this need to rewrite history. Nobody in this thread is objecting to the use of the term. Even the wikipedia article says the term was resurrected in the 80s.
