Abstract
This paper describes the results of a survey regarding the video game industry. From the sales date calendar printed in Famitsu, the release delay rate for Playstation and Playstation2 game titles were calculated. The results are:1) for both the Playstation and Playstation2, the rate was higher in the second year after being launched, then decreased afterward; 2) the rate for the Playstation is higher than that for the Playstation2; 3) although the rate decreases during the Christmas season in Playstation, that of the Playstation2 increases. These results indicate that the video game industry on the whole has acquired development know-how over these years, but that the pressure from the market on development is increasing.
