In this paper, we propose a 3D content display system that displays advertisements in a 3D content area according to the movement of a 3D character when 3D content is executed using a user terminal, and displays 3D advertisements corresponding to user information And a method for providing the same. Among the 3D contents, the advertisement providing system inputs user information for a plurality of users, executes 3D contents using the inputted user information, and displays advertisements in a

... predetermined 3D contents area during execution of the 3D contents. It can be used easily by linking with existing 3D contents production engine, and it can help to diversify profit models of individual developers of 3D contents and venture developers. We hope that this will help develop the game and 3D contents industry.
