John Malone's Liberty Media and Rupert Murdoch's News Corp confirmed Friday that they had agreed on a swap in which, essentially, Murdoch would turn over News Corp's controlling stake in DirecTV to Malone, and Malone would turn over his 16-percent stake in News Corp to Murdoch. The deal also calls for News Corp to hand over three regional cable sports networks and $550 million in cash to Liberty. The deal ends a long dispute between Murdoch and Malone during which Murdoch imposed a "Poison pill" defense against Malone to prevent him from gaining control of News Corp.
