Media tycoon Rupert Murdoch is closing in on a deal to buy the Dow Jones media and financial information group according to the weekend's news reports. News aggregation service Factiva is part of the Dow Jones group following last year's acquisition of the remaining half from Reuters.

At the centre of Murdoch's bid is the Wall Street Journal newspaper, which "Dirty Digger" as Murdoch is affectionately known, covets. The Financial Times believes Australian Murdoch will raise his bid for the group to the expected $5bn. A series of alternative bidders may also surface, including Thomson-Reuters rival Bloomberg, General Electric, Yahoo and even the FT's parent company Pearson.

A potential stumbling block for Murdoch has been his reputation for meddling in editorial matters. The Bancroft family, which holds 64% of the voting power at Dow Jones has now agreed to meet with Murdoch to discuss these issues and it is reported that Murdoch is minded to offer the family a seat on the News Corp board, his news empire.

The Wall Street Journal is revered for its editorial independence and there is great concern that ownership by Murdoch will erode this.

Unlike News Corp, the Dow Jones group has been very successful at the transition from print to online information delivery, with the Wall Street Journal charging online users, just as it does offline. Murdoch's online attempts have so far not been as successful and he could benefit from an infusion of Wall Street ideas.
