She went undercover as a Playboy bunny.
Gloria Steinem got her first break in the 1963 investigative reporting piece, "A Bunny's Tale." It was later made into a movie starring Kirstie Alley as Steinem, naturally. The young Gloria went undercover at the Playboy Club in New York City, keeping a diary that you can now read online. The piece, billed as Show magazine's "first exposé for intelligent people," uncovered the objectifying and not-so-glamourous realities of being a bunny and helped make Steinem a household name.
