Entertainment Software Rating Board - ESRB is an organization founded in 1994 by Entertainment Software Association (ESA). ESRB regulates and assigns classifications to the entertaining materials according to age and content, requires this type of industry to adopt certain advertising lines and ensure responsible online privacy principles for video and computer games and to other entertaining programs. ESRB activates in Canada and USA. ESRB classifies games according to their content, such as the movies classification system used in most countries. The purpose is to help consumers to determine after the type of content if the game is adequate or not for the user. Game's evaluation is shown on the cover, support, commercials and on game's site. The evaluation system is strictly volunteer, but almost all games are sent for evaluation because many magazines forbid selling unevaluated games and most game console producers does not licentiate a game unless it has the ESRB evaluation logo.
