Federal regulators in the US have fined the CBS TV network a record $550,000 (£306,814) for pop star Janet Jackson's "wardrobe malfunction" in February.
Jackson was exposed during a routine with Justin Timberlake
The singer exposed her right breast during a dance routine with Justin Timberlake at this year's Super Bowl.
Now the FCC (Federal Communications Commission) has fined 20 CBS-owned TV stations the maximum penalty for indecency - $27,500 (£15,340) - each.
The fine is the largest ever levied against a US television broadcaster.
However, the agency's five commissioners decided not to fine CBS's affiliate stations - more than 200 in all - which also aired the show.
The breast-baring incident generated a record number of complaints - more than 500,000 - and CBS was quick to apologise.
Timberlake blamed the exposure on a "wardrobe malfunction", while Jackson said it had been an accident.
In March she told chat show host David Letterman a second piece of material had been in place to conceal her breast when Timberlake ripped off her bustier.
"The US constitution is generous in its protection of
free expression, but it is not a licence to thrill," FCC
chairman Michael Powell said.
"The context of the half-time show leads us to conclude that the breast-baring finale was intended."
