Pinko and pink were widely used during the Cold War to label individuals accused of supporting the Soviet Union, including many supporters of ex-vice president Henry Wallace's 1948 U.S. presidential campaign with the Progressive Party. The word was predominantly used in the United States, where opposition to Communism grew strong among the population, especially during the McCarthy era. It was also in common use in South Africa during the apartheid era. In his two presidential campaigns, Alabama governor George Wallace often railed at "the left-wing pinko press" and at "pseudo-pinko-intellectuals.
Some of the most infamous uses of the term pink came during future president Richard Nixon's 1950 Senate campaign against Helen Gahagan Douglas: "She's pink right down to her underwear!" — a play on the fact that, at the time, pink was the usual color of women's undergarments. Nixon regularly referred to her as "the Pink Lady", and his campaign distributed political flyers printed on sheets of pink paper.
Archie Bunker, the patriarch of the Bunker family in the 1970s sitcom "All in the Family" often derisively used the term 'pinko' when referring to his liberal son-in-law Michael "Meathead" Stivic or Michael's friends.
Recently, the term was used repeatedly on the television series John Safran vs God when Safran is referring to his target demographic. Safran is likely to have intentionally referenced Daniels' "Uneasy Rider", and notably Safran had on a previous episode infiltrated the Ku Klux Klan.
