The TV Parental Guidelines
The Parental Guidelines are modeled after the familiar movie ratings which parents have know and valued for nearly 30 years. They are designed to be simple to use, easy to understand and handy to find.

Understanding the Ratings System
The ratings system required by the US Federal Communications Commission was first put into use in January 1997 by cable and broadcast television, with all shows bearing a rating in the upper left-hand corner, except for news telecasts. This system is used with the new V-Chip control device, which, according to who you ask, can be a way for parents to either keep their kids safe, or could be the beginnings of government censorship. Again, this is all according to who you ask.
