Facebook’s move to the top spot shows just how quickly the site has grown in popularity. Within the span of six years, Facebook has become the world’s largest Web social network with roughly half a billion users worldwide.
However, when all of Google’s properties are considered — such as YouTube and email, for instance — Google still reigns as the most visited site at 9.9 percent between January and November 2010. Facebook follows at 8.9 percent. Yahoo and all of its properties ranked third at 8.1 percent. ( Reuters )
