Look out, CNBC

For years, Fox News boss Roger Ailes -- the guy who invented NBC's business-news channel CNBC -- has been threatening to launch a Fox version. But it's always been held up by the difficulty of obtaining carriage agreements, that is, getting cable systems to agree to carry a new channel. But there are reports this week that Time Warner Cable has signed a deal for a Fox biz-news channel as part of a large agreement involving carriage of Fox News and other Fox networks. With Time Warner lined up, other cable deals will probably fall quickly into place, and CNBC will soon be facing some potent competition.
