A probate court in Nevada has begun reviewing evidence to determine who gets to control Rupert Murdoch's media empire after his death.

Evidentiary hearings in the case are scheduled to run until next week - with the court keeping the hearings closed to the public and the media.

Australian correspondent Murray Olds says Rupert aims to ensure control of the businesses is kept in the hands of his oldest son, Lachlan, to preserve their commercial value.
