The first use of the text speak phrase OMG ('oh my God') has been discovered - in a letter to Sir Winston Churchill.
A letter published by the US Library of Congress from Admiral John Arbuthnot "Jacky" Fisher to Churchill sent in 1917 contains the phrase.
It is used in reference to some "utterly [upsetting]" headlines.
"O.M.G (Oh! My! God!)-- Shower it on the Admiralty!!" wrote Fisher.
It was first re-published by Letters of Note.
