Justin Timberlake's new video for "Tunnel Vision" has a jillion moments of female nudity, boobs with nipples included. YouTube/Google has given it a pass and posted an explicit version, saying: "We make exceptions when [nudity] is presented in an educational, documentary or artistic context, and take care to add appropriate warnings and age-restrictions.”
(Video below is probably NSFW, but if it IS Safe For Work where you are I totally want to know more!}
Recall that on February 1, 2004 the nation lost its mind (or the media did and CBS had to deal with fines) as we were exposed to a mammary gland from a fellow mammal during the Super Bowl halftime show with Timberlake and Janet Jackson. The top of her bustier was pawed at on the line "I'm gonna have you naked by the end of this song" so some kind of exposure was planned. The "wardrobe malfunction" excuse never, well, covered it.
This is progress, I guess?
