Considering that only 6 months ago Facebook and MySpace were at roughly the same number of members, it begs the question, how has facebook managed to double it's membership in such a short space of time. A report released by TechCrunch (citing ComScore data) shows Facebook with 222 million in December compared with 125 million for MySpace. On top of this, Facebook also counted nearly twice the number of page views, with 80 billion in December compared with MySpace's 43 billion.
The main reason given by MySpace for it's slow down in membership growth is due to a strategic shift in overall company strategy. MySpcae has said, "[it's now] laser focused on building a sustainable global business which we measure by profits and revenue -- not just eyeballs."
Further to that, MySpace added that it "continues to dominate the U.S. market -- where the bulk of online advertising revenues reside -- both in terms of monetization and user engagement with more than 76 million unique users and a 40% spike in engagement year over year."
