Mobile app developers have always appreciated voluntary programs that help us provide a better experience for our users. The Cellular Telephone and Internet Association (CTIA) has wisely enlisted the Entertainment Software Ratings Board (ESRB) to produce a new initiative that can be a valuable resource to app developers and parents. Having effectively served as a guide for parents to choose appropriate video games for their children, ESRB is well-positioned to provide advisements for similar applications on mobile devices. Games on mobile devices now account for fifteen percent of industry revenues and this figure is growing. The CTIA/ESRB offering is a welcome addition to the self-regulatory efforts underway to provide greater consumer choice and transparency in the nascent mobile apps marketplace.
