When and where did emoticons first appear?

I want to know. Have they been around since the days of the typewrter, or are they something new?|||1972.|||Since I saw :) on my RCPM in 1980, the "first time it was used was ... 1982" is a little late. I'd guess that they started pretty soon after text messages (not the kind we have today) started - in the early 60s, but I have no "old tapes" to prove it. There's also a claim of 1979 for -) (Kevin Mackenzie).
