Facebook knocked Google from its cushy No. 1 slot this year, becoming the most-visited website in the US, Reuters reports. Between January and November, Facebook saw 8.9% of all US visits; Google.com saw 7.2%. If you count all of Google’s properties, like YouTube and Gmail, however, Google takes 9.9%, surpassing Facebook. Yahoo’s properties came in third, with 8.1%. Google was king in 2009 and 2008; MySpace was on top in 2007.
