Is Fox Business already playing dirty?

NBC Universal's CNBC had ads scheduled to run on the front page of Marketwatch.com today. But then out of the blue, the agency what bought the ad space on behalf of CNBC got word from the folks at Marketwatch.com that they won't be able to run the ads after all. Hmmm? Is it a coincidence that, Marketwatch.com is owned by DowJones which is about to be taken over by Rupert Murdoch, whose new business network launches today? Is this the doings of Newscorp? Does Murdoch and company already have their hands in the DowJones pot? If this is the case, then no one should be surprised due to the fact that Fox Business Chairman and long time Murdoch lieutenant Roger Ailes is known for riding dirty! In early September, CNBC negotiated and signed a contract with Dow Jones to buy advertising that was to run today on two Dow Jones Web sites, MarketWatch and The Wall Street Journal site. Last Tuesday night, CNBC’s ad buyers received a call from a Dow Jones representative saying that those ads could not run today, the first day of Fox’s competing channel. In the case of MarketWatch, CNBC had bought both an introduction ad for the site — meaning that every user on the site today would have seen an ad for CNBC before getting to the MarketWatch home page — as well as what is called a “road block” of ads — meaning CNBC would have been the exclusive advertiser on the site’s home page today.
