NEW YORK ( TheStreet) -- U.S. newspaper Web sites drew an average monthly audience of 105.3 million unique visitors in the fourth quarter of 2010, according to comScore and the Newspaper Association of America, and drew 62% of all adult Internet users.

In total, visitors generated an average of 4.1 billion page views per month and spent nearly 3.4 billion minutes, or 2.4 million days, browsing those pages.

Data released from Nielsen showed that in the fourth quarter of 2009, visitors generated 3.2 billion page views and browsed for 2.4 billion minutes, or a total of 1.7 million days.

"Newspaper Web sites stand out in today's online environment, with trusted brands and high quality journalism attracting an impressive audience that sets them apart from other players in the digital space," NAA president and CEO John Sturm said. "As publishers continue to reinvent their business models, digital is at the forefront of a multiplatform transition that has seen steady growth in online advertising revenue."

Newspaper sites reach 58% of browsers between the ages of 25 and 34 and 73% of individuals in households that earn a yearly salary over $100,000.

Major newspaper publishing companies are preparing to release their fourth quarter and full year earnings results in the coming weeks, and are looking to their digital divisions to offset weaker print results.

The New York Times ( NYT), which is scheduled to report its financial results on Feb. 3, is hoping that its digital offerings will help boost its earnings. In the third quarter the company reported that a 14.6% increase in digital advertising revenue partially offset its 5.8% decrease in print advertising revenue.

"Online advertising revenue, which rose 15%, continued to grow its share of revenue and made up 27% of the company's total advertising revenues in the third quarter," president and CEO Janet Robinson said in the quarterly report. "We remained focused on our comprehensive digital strategy, which includes increasing revenues from our digital sources, introducing new products and innovations that increase user engagement and extending our reach to new audiences across an array of devices."

Gannett ( GCI) also saw a boost from its digital segments in the third quarter. Digital revenue in its U.S. community publishing segment was up 10.2% in the quarter as digital advertising at USA Today increased 35.1%.

Gannett's total third-quarter digital revenue, including results from CareerBuilder and ShopLocal, gained 9.9% to $255.7 million and accounted for 19% of its total operating revenue.

The media company is scheduled to report fourth-quarter and full year earnings on Jan. 31.
