Rupert Murdoch said on Monday that News Corp. would not get into a fight with Microsoft over the acquisition of search engine Yahoo, confirming what most industry and Wall Street observers suspected. His statement came after a source familiar with the situation reported that Murdoch"s company had been in talks with Yahoo over a transaction to combine News Corp"s MySpace Internet social network and other Internet assets with Yahoo. "We"re not going to get into a fight with Microsoft, which has a lot more money than us," Murdoch told investors at the annual Bear Stearns media conference.
