WSJ_Mobile_Phone.jpgThe Associated Press reports that U.S. newspaper Web sites attracted 12% more visitors in the second quarter, “lending statistical credibility to the notion that Americans are increasingly getting their news online.”

Meanwhile, the online reach of newspapers topped 40%, according to Nielsen Online, up from 37.3% last year. “The latest audience figures provide further evidence that newspapers’ digital properties deliver highly accurate and hyper-local content that consumers can’t find anywhere else,” said Newspaper Association of America CEO John Sturm in the report.

Newspapers have raced to add video, graphics, blogs, user forums, mobile Web sites, and more; they’re also updating the sites more often, as Web readers tend to check in many times during the day for updates. Unfortunately, online advertising still only accounts for less than 10% of total newspaper ad revenue, according to the report.
