When I imagine who the first people were to use shorthand or text talk I think of someone in the last 30 years. I think of someone who was around when instant messaging and text messaging became popular. Well the term OMG was coined a little more than 30 years ago. It’s actually over 100 years old! Lord Fisher sent a letter to Winston Churchill saying “O.M.G.” and then he spelled out the word in parenthetical right after. I’m sure he had to explain this because no one had ever heard of it. I imagine this had to be more confusing to explain than trying to teach your parent the newest lingo.
