Ê Sirius XM Radio Inc. (SIRI, $0.07, $0.02, 30.18%) is seeking an investment from Liberty Media Corp., The Wall Street Journal reported, citing people familiar with the matter, in a last-ditch effort to fend off an unsolicited takeover approach from satellite entrepreneur Charles Ergen. The talks set the stage for a battle between the leading U.S. satellite-television providers - Liberty-controlled DirectTV Group Inc. (DTV, $23.28, $0.34, 1.48%) and Ergen's Dish Network Corp. (DISH, $12.90, -$0.08, -0.62%) - for control of the country's sole satellite-radio operator.
