New York—Dow Jones & Co. announced Tuesday that The Wall Street Journal will make design and content changes to better serve existing readers and attract new ones. The changes will be introduced over the next few months, culminating in January 2007 with a reformatting of the U.S. Journal’s web width to the industry standard 48 inches from its current 60 inches. To accommodate the changes, the Journal will retrofit 19 presses over the next 15 months. The capital cost of the project is estimated at $43 million, with estimated cost savings of $18 million a year beginning in 2007 from reduced newsprint consumption, Dow Jones said. In addition to the size change, the Journal will make navigational changes on its Web site, at www.wsj.com, to make accessing Journal content faster and easier for readers, the company said.
