The Wall Street Journal reports on itself, again. In a move that surprised no one, News Corp. Chairman Rupert Murdoch named Wall Street Journal Publisher Robert Thomson as the paper's new managing editor and editor in chief of Dow Jones. As managing editor, he succeeds Marcus Brauchli, who left under pressure last month. As a result, he will continue to oversee editorial operations at Dow Jones Newswires, as he had when he was publisher. Les Hinton, chief executive of Dow Jones, will add to his duties the position of Wall Street Journal publisher. Mr. Thomson sent an announcement to the Journal staff Tuesday evening that said, "I am deeply honored by this appointment and look forward to working closely with you all. This is a news operation with enormous potential, both in the U.S. and around the world. I have no doubt that, together, we will realize that potential."
