Peter Wanless, NSPCC chief executive, said: "This report demonstrates just how disturbingly easy at the time it was for Savile to get away, unchallenged, with despicable acts against children at the BBC. The impact on his victims has been profound - as we have already witnessed from calls to our helpline.
"It is tragic that a culture existed at the BBC in which Savile became too powerful to confront, so allowing him to use his celebrity status to abuse at will, leaving a trail of devastation in his wake.
"The BBC must ensure staff can easily raise concerns and that robust safeguarding procedures are in place to effectively act on these so that a scandal of this kind, never mind this magnitude, is never repeated."
A former Jim'll Fix It producer said he thought Savile's presence was "unnerving" to children.
Katrina Rose was just 14 when she was abused by Jimmy Savile but told ITV News she fears a similar scandal could happen again now.
Jimmy Savile's abuse could have been stopped if people had listened to "the small voice standing up against authority", Lord Hall has said.
