Rupert Murdoch must be hoping October is his lucky month. Today he launches the Fox Business Network, his long-awaited financial TV news channel, in America. It comes exactly 11 years after he created the Fox News Channel. Then the sceptics thought Murdoch stood little chance of usurping CNN, the pioneer of 24-hour news. A decade later Fox News is number one, with its unashamedly Right-of-centre agenda, and Rupert's News Corporation is hoping to repeat the trick again with FBN. He has even got the same man in charge, Roger Ailes, who launched Fox News.
