The director general of the BBC has apologised to the victims of Jimmy Savile and Stuart Hall.
Lord Hall said: "The BBC failed you when it should have protected you.
"I'm deeply sorry for the hurt caused to each and every one of you."
He added: "Savile committed his crimes in many places but it was the BBC that made him famous.
"What this terrible episode tells us is that fame is power, a very strong form of power.
"And like all power it must be held to account, it must be challenged and it must be scrutinised, and it wasn't."
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.
