You could see this coming a mile away.
Hitwise is reporting a major milestone reached by Facebook. They were the most visited site in the U.S. last week, topping Google for the first time.
We saw hints that this milestone would come. Facebook beat Google for the first time in single day traffic on Christmas, followed by New Year's, Valentine's and some recent snow days. The social network also was the top place to go to discuss all thing Winter Olympics.
Facebook also saw a 10% increase in search volume query in the month of February, a month when most search engines saw their query volume decline.
Facebook's traffic last week was 185% higher than the comparable week in 2009. Combined, Facebook and Google made up 14% of all web traffic in the U.S. last week.
