'game-changer' originates from the combination of 'game' and 'changer', where 'game' refers to a structured form of play or sport, and 'changer' implies something that alters or modifies.

The term 'game-changer' evolved from the sports context, where a single play or player could change the outcome of a game, to a broader usage in business and technology.

Initially, it referred to a pivotal moment in sports, but over time it evolved to describe any significant change in various fields.
