Super Bowl XXXVIII halftime show controversy
The Super Bowl XXXVIII halftime show, which was broadcast live on February 1, 2004, from Houston, Texas, on the CBS television network, is notable for a moment in which Janet Jackson's right breast and nipple—adorned with a nipple shield—was exposed by Justin Timberlake to the viewing public. The incident, sometimes referred to as "Nipplegate" or "Janetgate", led to an immediate crackdown and widespread discourse on perceived indecency in broadcasting.
