In the first few years of social networking, MySpace was the big name. Between 2003 and 2006, it grew to 100 million users, and by June 2006, the website was even more visited than Google. Then came Facebook.By 2008, Facebook had surpassed MySpace in worldwide users, and in United States users a year later. As MySpace declined (it dropped to approximately 25 million users in June 2012), some businesses wondered about making a major advertising investment in Facebook might it not also be displaced as MySpace was?Well, perhaps but in the meantime, Facebook has surpassed 950 million users (and about 145 million users in the United States, about 43 percent of the nation’s population). Other than Google.com, it is the single most visited website on the Internet, giving companies unprecedented access to potential consumers.
