The UK media watchdog Ofcom has ordered broadcasters to be more careful about showing sexually explicit music videos before 9pm.
Ofcom issued the new guidance so as to tighten the enforcement of existing watershed rules.
Broadcasters have been told to take particular care masking or editing offensive language where possible, in order to protect children.
The new guidelines follow the controversy over the final of The X Factor last year, which attracted 4,500 complaints to Ofcom due to raunchy performances by Rihanna and Christina Aguilera (For full article see Ben Dowell, The Guardian).
