More people spend a lot of time on the Internet

Almost half of U.S. adults now spend more than an hour a day using the Internet, according to a Gallup survey. Frequent Internet use surged during the past year among some demographic groups, particularly men, post-graduates, people aged 18-29, seniors, unmarried people, single people and the unemployed. However, frequent Internet use slipped slighlty for some cohorts, including college graduates, people aged 30-49 and high-income earners.
