Mr Chenin will also become chairman and chief executive of Fox Television Group, part of Fox Group.
Mr Carey will continue as chairman and chief executive of Fox Television Group.
"These appointments are designed to strengthen management and coordination of the company throughout the world," Mr Murdoch said.
Media analysts said the appointments signalled that Mr Murdoch was trying to strengthen the company's programming business as he expanded satellite and broadcast television around the globe.

The office, besides Mr Chernin and Mr Carey, will consist of Rupert Murdoch, chief executive and chairman, David DeVoc, chief financial officer, and Arthur Siskind, general counsel.Reuse content
