Another one bites the dust: Les Hinton, chief executive of Rupert Murdoch’s Dow Jones & Co., announced Friday that he will step down, but says he was "ignorant of what apparently happened" while he was overseeing Murdoch's British tabloids. Hinton has been a top deputy to Murdoch for decades and ran News International, the British arm of Murdoch’s media empire, for a dozen years. In 2007, he swore to Parliament that phone-hacking at the tabloid News of the World was limited to just one rogue reporter—but in the past week numerous allegations have suggested that the corruption was much more widespread. Today, News International Chief Executive Rebekah Brooks announced her own departure.
