According to market research firm comScore, Facebook now has more than twice as many U.S. users (111.9 million) than it did in 2008 (54.5 million). To put that into perspective, no other Web company since Google has been as successful as Facebook, which now earns about $2 billion in profit every quarter.
"Ever since it opened registration to the general public back in the fall of 2006, Facebook has seen considerable growth, so it's not like this story is new by any stretch of the imagination," comScore noted. "And yet, even in its native market, Facebook continues to add to its audience at an incredible rate... It now accounts for 7 percent of all time spent online in the U.S."
And it's not just the number of users that so impressed comScore, either. The research firm noted that Facebook manged to "grow substantially across nearly every performance metric," including total pages viewed, average visits per visitor, average minutes per visitor, and several more.
