ishmintingas was correct in his reply. While you won’t see totally naked people on CBS or any of the other major networks (With a notable exception . . . when * Schindler’s List * was aired unedited) you can see plenty of nekkid folks on PBS when they run documentaries on other cultures. TLC and Dicovery Channel often run documentaries on the human body in which they show nudity, as well as The History Channel’s documentary * History Of Sex. * The list could go on and on.
Print media is also not shy about nudity. * National Geographic * comes to mind as a primary example.
It also depends on your definition of nudity. The television program * ER * had a bit of flack a few years ago when it showed a young woman’s naked breasts. Their arguement was that the nudity was not salacious (the young woman had just had surgery to remove a cancerous lum, IIRC) and the furor died down rather quickly. * NYPD Blue * showed a man’s nude buttocks on a few occasions as well.
As a further comment on naked people/sexual arousal:
Opinions on what is erotic varies greatly throughout cultures and time. In the Victorian era of extreme prudery, the sight of a woman’s exposed ankle was enough to get men hot and bothered because women wore long, concealing dresses, and a lady could only show the tips of her shoes. It’s the RESTRICTION of nudity which makes it erotic. It’s, in a way, the forbidden fruit.
I’m sure a man from a Muslim country where women are concealed head-to-toe, and had never been exposed to Western culture and modes of dress, would consider an exposed face, or arm, or hell, even a shoulder to be erotic, simply because it isn’t what he’s used to seeing.
While in Amazonia, a guy sees a woman’s breasts every day, to the point where they become as “natural” a part of her as her face, and are no more erotic than seeing the back of a woman’s hand.
Just as a sort of example: In * Memoirs of a Geisha * (which is one of the more accurate portrayals of the geisha world, I’ve read) one of the geisha explains that the point of the white makeup is to make men more aware of the naked skin beneath. The geisha would leave a tiny margin of skin around the painted mask to exaggerate the effect. So covering what is common to us, the naked skin of the face, actually made the common erotic.
