Spoken used to show that you quite agree with what someone is saying or that you think they are just Allen Walker Read identifies the earliest known use of OK in print form in 1839, in the March 23 edition of the Boston Morning Post. The announcement of a trip through the Anti-Bell Ringing Society (a “frolicsome group” according to Read) caught the attention of Boston`s Land newspapers. Charles Gordon Greene wrote about the event with the line widely regarded as the first instance of this variety of OK, with brilliance: spoke as a response to the assertion that you quite agree with someone As adjective, OK mainly means “reasonable” or “acceptable” as a contrast with “bad” (“The boss authorized this, so it`s ok to send”); it can also mean “mediocre” if used as opposed to “good” (“The fries were great, but the burger was just ok”).

The OK key can probably be traced back to the user interface search for the Apple Lisa.  The inspiration was probably the setting -ok in Unix`s “Find” command.  Good question.
