What is the single quality that has made Rupert Murdoch the richest and most powerful media mogul of our age?

As the News Corp chairman announced plans to (semi) retire in November Press Gazette asked some of his closest former colleagues: What is the Murdoch factor that has driven his success?

Over the course of 70 years, Murdoch built up a media empire worth more than $100bn at its peak. He sold the entertainment arm 21st Century Fox to Disney for $71bn in 2017 (including News Corp’s 39% stake in Sky). Sky was then sold to Comcast for £30bn the following year. News Corp today has a market cap of around $12bn and includes Fox News, Harper Collins, Dow Jones, The Sun, the Times titles, the Wall Street Journal and the New York Post.
