Much of Savile's career involved working with children and young people, including visiting schools and hospital wards.
He spent 20 years presenting Top of the Pops before a teenage audience, and an overlapping 20 years presenting Jim'll Fix It, in which he helped the wishes of viewers, mainly children, come true.
The scandal was a major factor leading to the establishment of the wider-ranging Independent Inquiry into Child Sexual Abuse which was announced by the Home Secretary, Theresa May, in July 2014.
The BBC showed two Savile tributes over the 2011 Christmas period, and it was alleged that the Newsnight report had been dropped because its content would have compromised the showing of the tributes.
A joint submission to the Leveson Inquiry from Anna van Heeswijk (Object), Jacqui Hunt (Equality Now), Heather Harvey (Eaves) and Marai Larasi (End Violence against Women) was titled "Just the Women", a phrase which was reportedly written by Newsnight editor Peter Rippon in an email to a colleague concerning the lack of other authorities [than the alleged female victims] for evidence of Savile's abuse.
It described the alleged abuse as being "on an unprecedented scale", and the number of potential victims as "staggering".
The report of the investigations undertaken jointly by the police and the National Society for the Prevention of Cruelty to Children (NSPCC), Giving Victims a Voice, was published on 11 January 2013.
During his lifetime, two police investigations had looked into reports about Savile, the earliest known being in 1958, but none had led to charges; the reports had each concluded that there was insufficient evidence for any charges to be brought related to sexual offences.
In October 2012 it was announced that the Director of Public Prosecutions, Keir Starmer, would investigate why proceedings against Savile in 2009 were dropped.
Culture Secretary, Maria Miller, said she was satisfied the BBC was taking the allegations very seriously, and dismissed calls for an independent inquiry.
Labour leader Ed Miliband said an independent inquiry was the only way to ensure justice for those involved.
He said that Savile had sexually assaulted victims aged between five and 75 in NHS hospitals, and apologised to the victims.
Further investigations, in hospitals and elsewhere, led to additional allegations of sexual abuse by Savile.
The founder of Child Line, Esther Rantzen, was shown the interviews by Williams-Thomas and commented that "There were always rumours that he [Savile] behaved very inappropriately sexually with children." Derek Chinnery, controller of Radio 1 from 1978 to 1985, recalled an occasion when he confronted Savile, saying "I asked, 'what's all this, these rumours we hear about you Jimmy? There was no reason to disbelieve." As a result of the shelving of the Newsnight investigation into Savile's activities (see above), there were complaints on Newswatch.
