Many believe It was originated in the 80s. Really we can find interesting traits from the 30s. What I love to read is Alfred #Korzybski who had a school for semantics in New York. He already talked about the importance of using #language to for example overcome behavioural traps or emotions. It is interesting, isn’t it, to observe the power of language. Every word we speak makes the brain make inner stories and movies whether we are aware of it or not. I can only say: Be aware of the words you use!
