The Entertainment Software Rating Board (ESRB) is a non-profit, self-regulatory body established in 1994 by the Entertainment Software Association (ESA), formerly known as the Interactive Digital Software Association (IDSA). ESRB assigns computer and video game content ratings, enforces industry-adopted advertising guidelines and helps ensure responsible online privacy practices for the interactive entertainment software industry.
A gauge of content but not quality, the system helps parents decide which game should be age-appropriate for their children. The ESRB system is applied to every game sold in the United States.
