RIP: Helen Gurley Brown, at 90

"Quintessential Cosmo girl" and magazine pioneer Helen Gurley Brown, who helped spur the sexual revolution by declaring that women could "have it all," including a career, marriage and great sex -- died this morning after a brief hospitalization. She was 90.

Gurley Brown ran Cosmopolitan for four decades, transforming it in the 1960s with a sexually frank tone that she made famous in her 1962 bestseller, "Sex and the Single Girl."

The industry icon retired from Cosmo in 1997, but she continued to make an appearance in her pink corner office at Hearst nearly every day until her death.
