Michael Bloomberg has expressed the desire to own a big-name newspaper over the years but has not reached out to Rupert Murdoch to discuss a possible purchase of Dow Jones and its flagship paper the Wall Street Journal, sources told Reuters. News website Axios reported earlier on Friday the billionaire owner of Bloomberg L.P. was interested in acquiring either WSJ parent Dow Jones from Murdoch’s News Corp, or the Washington Post from Amazon.com’s Jeff Bezos, citing a source familiar with Bloomberg’s thinking.
