a family trust that benefits his four children from previous marriages - Prudence, Elisabeth, Lachlan and James. The latter three have had active roles in the companies.
Upon Rupert Murdoch's death, all four will have an equal say in what happens to the roughly 38 percent voting stock the trust holds in both companies.
He and Wendi Deng Murdoch, 44, have two school-age daughters, Grace and Chloe. They are beneficiaries of 8.7 million non-voting shares being held in a separate trust.
Wendi Deng Murdoch is a Yale graduate who worked as a junior executive at News Corp.'s subsidiary Star TV in Hong Kong, where she met her now-husband at a 1997 cocktail party. She left Star TV before marrying the media mogul in 1999 aboard Murdoch's private yacht, in New York.
She produced the 2011 movie ''Snow Flower and the Secret Fan,'' released by News Corp.'s Fox Searchlight.
Wendi Deng Murdoch literally leaped into the spotlight when she jumped up to smack a protester who was throwing a cream pie at her husband during a 2011 British parliamentary hearing into phone hacking by News Corp. newspapers.
