1973: PBS aims to make plays less boring with breasts

PBS became the first network to intentionally reveal a woman's breasts and nipples with its serialized version of Bruce Jay Friedman's play Steambath. The series positions a steambath as the afterlife; future Hulk Bill Bixby as God; and Valerie Perrine as... the above lady. Perrine was shown from the side taking a shower, and the scene was so daring at the time that only a few PBS affiliates deigned to carry the show. Steambath ultimately ended up showing a few bare male buttocks as well, but it's Perrine's scene that remains a touchstone in TV nudity.
