Years before her husband Al was elected vice president of the United States, Tipper Gore established a reputation of her own, as a social issues advocate. And her issue, in the late 80s, was protecting America's children from sex and violence in the media.

She was co-founder of the Parents Music Resource Center, which led the effort to require warning labels if on media contained profanity, sexual references, or violence.

I met her in 1987. She had just published a book called Raising PG Kids In An X-Rated Society.
