I am surprised you ask but I have assumed you have heard of George Orwell's 1984 because it is well known.
Orwell's novel, 1984 describes the Ministry of Truth which Orwell based on the BBC. Behind the scenes Big Brother manipulated everything using newspeak and double think. The Ministry of Truth was Big Brother's platform for giving out information to control everyone.
1984 is supposed to be a criticism of the left from the left. Many feel it reflects the way Watchtower acts. I added in the information about Jimmy Savile because this man (in the UK) had a bad reputation among his colleagues in the BBC but nothing was ever done about him. Given what we have learnt about Watchtower's cover ups from the Australian Royal commission etc I thought I'd add it in.
