Where does ‘Hello world’ come from?
"Hello world!" is the most commonly used example I can think of, yet I don’t really know where it came from. Was it used by some particular book, or did it just spread among developers? Did people write "Hello world!" snippets in COBOL or FORTRAN ?
Just a quick search on wikipedia gaves :
