The Wall Street Journal is ready to start charging for mobile access on the Blackberry and iPhone, News Corp . CEO and chairman Rupert Murdoch told attendees at the Goldman Sachs Communacopia XVIII Conference. He didn’t offer a time frame for the charges, but indicated it would it start in a few months. Further down the road, Hulu can be expected to institute some sort of pay-per-view or subscription model, Murdoch said. The details there have yet to be worked out with NBC Universal and Disney , along with other content providers. Additionally, Murdoch expressed some displeasure with Amazon’s Kindle. He much prefers the terms with Sony, though he didn’t offer specifics. Although Amazon hasn’t revealed its revenue split, it generally takes a 70 percent cut. (A recording of the webcast will be available here, later in the day).
