Rupert Murdoch is expected to announce Monday he will buy-out the shareholders of his Fox properties for about $7 billion. Executives involved in the deal said Murdoch is consolidating his global media empire in the United States. The deal would solidify Murdoch's control over some of the nation's most valuable media assets such as the Fox broadcast network and the DirecTV satellite service. Murdoch's News Corporation owns newspapers, TV, film and satellite assets around the globe. The right-wing media mogul's purchase of the remaining 20 percent of the Fox Entertainment Group gives him greater leverage to make more media acquisitions.
