An international society for the advancement of game theory and its applications, the Game Theory Society, began operations on January 1, 1999. The Game Theory Society promotes the investigation, teaching, and application of game theory.
Game theory studies strategic interaction in competitive and cooperative environments. It 
is a central tool for economics and the social sciences, poses challenging research questions in mathematics, and is applied across a wide variety of fields, including computer science, neuroscience, philosophy, and biology.
The Game Theory Society holds its World Congress every four years, including:
