New York—Dow Jones & Co., which is being acquired by Rupert Murdoch's News Corp., reported late Monday that ad revenue for its flagship Wall Street Journal
fell 7.2% in July on a 20.9% decrease in advertising volume. Technology advertising volume dropped 75.4% as decreases in communications, hardware, office products, technology professional services, software and other b-to-b technology advertising more than offset an increase in personal computers advertising. Ad revenue at Barron's
was off 9.5% in July due to declines in technology and classified advertising. Online advertising revenue at the Wall Street Journal Digital Network, which includes Barrons.com, MarketWatchcom and WSJ.com, as well as the company's vertical Web sites, grew 24% in July, fueled by increases in financial and technology advertising.
