From 1999 to 2001, a research study was conducted at the University of Pennsylvania Annenberg Public Policy Center to observe the use of the V-chip in family households. The study was conducted on a total of 150 families with children between the ages of 7 and 10 who had V-chip television sets in their homes. Over the course of a year, families' use of the V-chip technology was observed to draw conclusions about the overall use of the V-chip in family environments.
