It’s been a long time coming, but Facebook has finally passed MySpace in terms of total US uniques, according to comScore. In May, comScore reported 70.28 million US uniques for Facebook (up 97% year over year), compared to 70.26 million for MySpace (down 5% year over year).
By contrast, Compete reported 82.9 million US uniques to www.facebook.com in May, while Facebook itself reported 64 million monthly active users in the US during the month. The comScore numbers come out to 4% monthly US audience growth for Facebook in May, while the Compete numbers show 8%. Facebook’s self-reported numbers showed 5% growth. Here’s the full comScore chart:

The contrast from this time one year ago is incredible. In May 2008, MySpace was more than twice as big as Facebook, and Twitter was barely a blip on the radar. Today, Facebook is in the lead, MySpace is slightly down, and Twitter’s reach has grown by almost 2700%.
Meanwhile, HitWise also reported today that Facebook’s overall share of Internet visits is up from 2.9% of all visits in the beginning of May to 3.6% when the Facebook username floodgates opened on Saturday.
