When Ms. was launched as a "one-shot" sample insert in New York Magazine in December 1971, few realized it would become the landmark institution in both women's rights and American journalism that it is today. Ms. was the first national magazine to make feminist voices audible, feminist journalism tenable, and a feminist worldview available to the public. Today, the magazine remains an interactive enterprise in which an unusually diverse readership is simultaneously engaged with each other and the world.
