broadcast and cable networks in response to concerns from parents and advocacy groups regarding increasingly explicit sexual content, graphic violence and strong profanity in American television programming, and was designed to be used in conjunction with the V-chip, which the U.S. government had mandated to be built into all television sets manufactured from 2000 onward (and the vast majority of cable/satellite set-top boxes).
