Those who read online newspapers tend to be better-educated. According to Pew, 44 percent of college graduates read an online paper on a daily basis, while only 11 percent of those with a high school education or less do so.

Moreover, the percentage of Americans who read a print newspaper on a typical day has dropped by about 40 percent since the early 1990s, while the proportion of those who watch the nightly network news on a regular basis also declined by one-half, eMarketer reported.

The demographic findings echoed those from the earlier study conducted by the Readership Institute, which found that those who read online newspaper tended to have higher education than those who do not, according to eMarketer.
