From a Wall Street Journal story about the use of Honorifics:

This is a special edition of Style & Substance, to discuss the just-announced decision on honorifics.

Last name only

The first edition of The Wall Street Journal in July 1889 used them, to be polite. So did the 100th edition in 1989, and every other right up until this week.

But as of Wednesday, you will no longer be seeing Mr. before a man’s name in Journal news articles. Nor will you see a Ms., Mrs., Miss or Mx.—the gender-neutral honorific that first appeared in the Journal in 2019.
