The Wall Street Journal's coverage [PREMIUM] of Thomson Financial's decision to replace Reuters-sourced news on its Thomson ONE advisory platforms with content from Marketwatch.com fills in many interesting gaps uncovered in Thomson's press release. The key additional fact is that MarketWatch.com is to expand its editorial staff by about 50 percent as a result of the deal, expansion which MarketWatch CEO Larry Kramer notes subsidizes their strategy to penetrate institutional trading more effectively. The press release notes that Thomson will call upon not only new staff but monitoring of deal channels such as Thomson's IFR to highlight and amplify key events in the securities trading marketplace. Reuters in effect brought the deal upon itself as it balked when it saw Thomson using Reuters news not only in the financial advisory space but as a key tool to penetrate institutional trading. While MarketWatch obviously lacks the global footprint of the Reuters news organization, it is a news outlet born of the Internet era, with edgy and savvy coverage and analysis of major deals and industry events via feeds and a highly respected and dynamic Web portal presence. Going toe to toe with Reuters and Bloomberg in the trading rooms is a leap up for MarketWatch, but it's perhaps an easier leap than it is for the global legacy of Reuters to respond as a culture to a new era of news that engages and rewards inter-organization collaboration more than ever before. It will be several months at the least before the full impact of this deal begins to be felt, but the race for Reuters to get a news product that responds more effectively to the demands of online-trained users is already hot.
