Where does the concept of the first program programmers learn to do is print hello world to the console originate from?

This seems to be a tech tradition as old as the mountains? Where does the tradition come from?

    There's an article on Wikipedia about that, is it of any help?

    The earliest ‘Hello world’ program I know of was Kernighan’s, written in B, which I mention in my answer about character literal syntax. There may have been some earlier occurrences of the phrase, though. May 12 at 20:16

    Re, "the first program programmers learn to do" That's somewhat misunderstanding the point of Hello World. I've been employed as a software developer for more than forty years, and I still "do" Hello World all the time. The point of Hello World is to prove that some new thing works at some basic level. (e.g., You can use it to prove to yourself that you have learned how to use a new toolchain to turn source code into something executable.) May 13 at 13:12
