According to another study conducted by the Entertainment Software Association in 2010, 40% of the game playing population is female, and women 18 or older now comprise 33% of all gamers. Also, the percentage of women now playing online has risen to 42%, up several percent since 2004. The same study shows that 46% of game purchasers are female (Entertainment Software Association). In recognition of the importance of the issues of women and girls as game developers and players, the International Game Developers Association, an association of companies and individuals in the games industry, has formed a special interest group on Women in Game Development. This is an active field of discussion and a topic in many conferences in the video gaming industry.
