The Videogame Rating Council (V.R.C.) was introduced by Sega of America in 1993 to rate all video games that were released for sale in the United States and Canada on the Master System, Genesis, Game Gear, Sega CD, 32X, and Pico. The rating had to be clearly displayed on the front of the box, but their appearance in advertisements for the video game was strictly optional. It was later supplanted by the industry-wide Entertainment Software Rating Board.
