George Orwell's 1984 was to be called 1948 but he and/or his publishers felt that would panic the readers. What he was saying would sound too close to home.
The British Broadcasting Corporation was Orwell's Ministry of Truth. The one in charge of everything was Big Brother. Big Brother used the Ministry of Truth to make people believe:-
“War is peace.
Freedom is slavery.
Ignorance is strength.”
"In the end the Party would announce that two and two made five, and you
would have to believe it. It was inevitable that they should make that
claim sooner or later: the logic of their position demanded it. Not
merely the validity of experience, but the very existence of external
reality was tacitly denied by their philosophy. The heresy of heresies
was common sense."
In UK the British Broadcasting Corporation gave us both Childline (a phone line for vulnerable children) and Jimmy Saville (a notorious pervert and child predator).
From Wikipedia
A significant part of Savile's career and public life involved working with children and young people, including visiting schools and hospital wards. He spent 20 years from 1964 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. During his lifetime, two police investigations considered 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.
Jimmy Savile's autobiography, As It Happens (1974) contains multiple admissions of criminal behaviour, apparently without Savile's self-incrimination being noticed. He would joke to the press when they phoned him "She told me she was over 16." Press investigations dating back to at least 1973 did not lead to the publication of any direct accusations being made against Savile, though rumours persisted and were intermittently mentioned in the print media for many years.
