Rupert Murdoch, the 92-year-old media mogul, is set to step down from his role as chairman of News Corp. and Fox Corp. and take on the role of emeritus chairman, with his eldest son Lachlan taking on the role of sole chair. Rupert will take on his new role at the companies' next shareholder meetings in mid-November, marking the end of a seven-decade career that saw him build a media dynasty and establish himself as one of the world's most influential media executives.
