## Origin

The words “zero-sum” indicates an equal or neutral emphasis on the outcome of the “game”. That means that the outcome total is zero, which indicates that one side wins and the other loses in exactly that proportion. It has originated in the 1940’s in the field of game theory.

Your definition of "Zero-sum" game is not precisely the meaning I learned years ago in relation to game theory. A zero-sum game is where there is no net gain by all parties to a game. That is, what one party's gain is in a game (or business) situation, results in an equal loss to any other parties in the game. Therefore a "win-win" situation cannot be a zero-sum game. Likewise, nuclear warfare cannot be a zero-sum game.

Note: A lottery or a casino operation is not a zero-sum game, because the house ALWAYS extracts its share of the game.- John April 4, 2021
