Rupert Murdoch’s News Corp (NWSA.O) and John Malone’s Liberty Media Corp (LINTA.O) are interested in NBC Universal, according to a report by CNBC, citing sources. Cable company Comcast Corp (CMCSA.O) has been widely reported to be in talks with NBC Universal parent General Electric Co (GE.N) to buy a controlling stake in the broadcast, cable and movie company… News Corp, which owns the Fox cable network and local TV stations, had been seen as a less likely bidder, analysts have said, because taking a stake in NBC might raise antitrust concerns with the U.S. government.
