American online users are spending more time on the Web, both on a daily and weekly basis, according to a recent study by Harris Interactive, eMarketer reported.

In 2008, at-home online access time far outstripped at-work access. Both are expected to grow this year.

However, according to another study by TNS Global, U.S. users do not take the lead in spending leisure time online. China topped other countries on the list, with users spending 44 percent of their leisure time on the Internet last year. The United States was ranked fifth, as users spend 30 percent of leisure time spent online, just after Italy (31 percent), but ahead of Spain and Australia (29 percent each), eMarketer reported.

However, the United States may improve in the rankings in coming years, according to Harris Interactive. Since 2001, the amount of time U.S. residents spent online per week jumped from seven to 14 hours. It increased slowly between 2001 and 2006, but accelerated in 2007 and boosted even more in 2008.
