The latest inquiry into British presenter Jimmy Savile says BBC staff turned a blind eye to his sexual abuse of up to 1000 girls and boys in the corporation's changing rooms and studios.
The Observer newspaper quotes from an internal inquiry by former judge Janet Smith.
It reports Ms Smith found executives at the world's biggest public broadcaster recognised Savile's behaviour but took no action to stop him.
A police investigation concluded last year that the television and radio presenter, who died in 2011 aged 84, was a predatory sex offender who abused children as young as eight over more than 50 years.
It identified 450 victims but the Smith inquiry suggests up to 1000 children were abused by Savile while he was working for the BBC.
Savile was one of the biggest TV stars in Britain in the 1970s and 80s, and used his fame as a presenter of the BBC chart show Top of the Pops and children's program Jim'll Fix It to rape and assault his victims.
But AFP reports the BBC is not the only organisation with questions to answer.
The health ministry is currently investigating alleged abuse of patients at state-run hospitals, while a police report last year found that officers had failed to follow up evidence against Savile dating back as far as 1964.
The publicity over Savile prompted a number of women to complain of abuse by other television stars from the same era, a number of whom are now facing criminal charges.
