In a recent answer about GM-ming in D&D, I had to resort to Rule 0, upon which doppelgreener did correctly point out that it is not universal about all games but the core of D&D mentality. In the chat then kviiri did point out that "The GM is always right" is actually a pretty crap rule on itself.

Now I wonder: Where and when did the rule 0 actually got codified as we know it now?

I have the faint feeling that it might have come from the origins of Pen and Paper in wargaming, but I can't put my finger on it more precisely.
