Parental Advisory is a message affixed by the Recording Industry Association of America (RIAA) to audio and video recordings in the United States containing offensive language and/or content. Albums began to be labeled for “explicit lyrics” in 1985, after pressure from the Parents Music Resource Center. In 1990, the PMRC worked with the RIAA to standardize the label, creating the now-familiar black and white design. To some, it has become known as the “Tipper sticker” because of Tipper Gore's visible role in the PMRC.
Some politicians have tried to criminalize the sale of explicit records to minors, and others have gone so far as to try to ban such records. Certain retailers refuse to sell albums containing the label, and many others limit the sale of such albums to adults only, although, most stores have settled on an age limit of 17 in order to buy an album containing the label. While the label is most prevalent on heavy metal, dance pop, alternative rock, punk and, especially, hip-hop/rap albums, it can appear on any genre of CD which the RIAA believes warrants the need for one.
