It was the first national feminist publication in the United States. Letty Cottin Pogrebin, Mary Thom, Patricia Carbine, Joanne Edgar, Nina Finkelstein, Mary Peacock, Margaret Sloan-Hunter, and Gloria Steinem were the initial editors. Beginning in 1971 as a one-time supplement in New York magazine, the first stand-alone issue of Ms. was released in March of 1972. Its mission was to "encourage women's rights and equality by presenting information about women's issues from all points of view—including those often excluded from other media." The magazine focused on issues such as abortion, child care, employment discrimination, domestic violence, sexual harassment, and women in combat. It also featured articles by prominent writers such as Alice Walker, Andrea Dworkin, Toni Morrison, and Maya Angelou. Ms. magazine had several influential people as founders or contributors. The first was Betty Friedan, who published an article in its first issue titled "The Problem That Has No Name." She went on to become one of the leaders of the modern women's movement with her book The Feminine Mystique, which described how many American women were unhappy with their lives. Another important founder-editor was Gloria Steinem, who became known for her campaigns for women's rights and social justice. Other notable contributors have included Jann Wenner, Lani Guinier, Susan Brownmiller, Ariel Levy, and Hillary Clinton.
