Fundamental Christianity and Conservatism in U.S.: The Parents Music Resource Center (PMRC)

Founded in 1985 and led by Tipper Gore, Senator Al Gore's wife. The other members in the group were Susan Baker( wife of Treasury Secretary James Barker), Pam Howar (wife of Washington Realtor Raymond Howar), Nancy Thurmond, and Sally Nevius (wife of Washington City Council Chairman John Nevius).

The groups aim was to shed light on what was being broadcast through means of the radio and television at that time.The PMRC spoke out against certain artists' material, deeming it inappropriate for children and wanted these songs to stop being broad casted.

'According to Tipper Gore, the PMRC was formed to alert the public of "the growing trend in music towards lyrics that are sexually explicit, excessively violent, or glorify the use of drugs and alcohol." '

'According to Tipper Gore, "this change in popular culture co-existed with the breakdown of the nuclear family.'

A list was compiled called "The Filthy Fifteen", on the list were fifteen popular songs that they believed dealt with very mature topics such as sex, violence, and drugs.
The rating system was as follows:

V for violence
O for references to the occult
D/A for overuse of drugs/alcohol
X for harsh sexual content

In the fight against these themes, the PMRC got multiple recording companies to put parental advisory stickers on albums that have certain material like that of the Filthy Fifteen.

Prior to that happening, the Senate held a hearing on what was called "porn rock".
Musicians Frank Zappa, John Denver, and Dee Snider testified at the hearing to protect their music.
