The statistic that really jumped out for us, however, was that in September 2009, the average U.S. Internet user spent an estimated 68 hours online (both at home and at work).

Although that still trails television usage by a significant margin, it’s clear that the Internet is carving out a greater and greater role in our lives each month.

In addition to spending an average of 68 hours online, the average user visits nearly 2700 websites and averages 57 seconds per site.

For the larger web brands, users spend an average of 1 hour 53 minutes a month on Google, 3 hours 8 minutes on Yahoo and 5 hours 24 minutes on Facebook. The usage study compliments another Nielsen report issued yesterday that reported a 25% increase in online video viewing year-over-year.

How much time do you spend online each month? Is there any other medium that gets more of your attention than the Internet (music, television, etc.)? Let us know!
