Sam Gustin knew it was only a matter of time. When Rupert Murdoch purchased Dow Jones , publisher of the Wall Street Journal , it was no secret that he hoped to leverage the paper's stable of business news reporters to boost Fox Business Network, his nascent competitor to CNBC. There was just one problem: CNBC and the Journal have an exclusive content partnership though 2012. Not so exclusive, it appears. Tomorrow, Walt Mossberg, the Journal's gadget guru, will launch a regular, weekly technology segment on Fox Business Network, Kevin Magee, executive vice president of Fox News, announced today . So how did FBN get around the CNBC/Journal agreement? There are loopholes, of course. (There are always loopholes.) "We can't just go ahead and use anything," Magee said at a conference earlier this year . "I believe the restrictions involve regularly-scheduled, branded segments. There is a carve-out for non-business news and there is a carve-out for breaking news." So tune in tomorrow to see Walt Mossberg discuss "non-business" or "breaking" news. Well, I guess that rules out any discussion of the new iPhone, set to go on sale on Friday. Perhaps he'll talk about the latest in the A-Rod divorce case.
