I'm writing an article about "personal oversharing" and thought it might be interesting to mention the origins of the expression TMI. Research has turned up the notion that it may have originated in the US military -- how this happened would be helpful if any of you happen to know this -- but I'm also interested in when it cropped up in present-day lingo. Duran Duran put out a single with the title "Too Much Information" in 1993, which suggests that it may have been in the vernacular at that point. Anyone have a general sense or might be able to point me in the right direction?
Thank you so much for your help in advance.
