According to Jeff Hackett, comScore senior vice president, in a statement, "The good news for publishers is that even as print circulation declines, Americans are actually consuming as much news as ever - it's just being consumed across more media. The Internet has become an essential channel in the way the majority of Americans consume news content today with nearly 3 out of 5 Internet users reading newspapers online each month."

comScore's Ad Metrix also shows that in April 2010, online newspapers accounted for 2.4 percent of impressions, and yet a higher 6.7 percent of display ad dollars among the top site categories. Online newspaper had the average cost per thousand impressions (CPM) higher than each of the other top site categories, at about $7, PR Newswire reported.

"Online newspapers represent premium inventory for advertisers," Hackett added.
