In May 2009, Facebook became the most popular US social networking site. Facebook totaled 70,278,000 unique visitors, up 97% from May 2008 to May 2009. MySpace hits shrank 5% over the same timeframe, fading to 70,255,000 unique visitors.
MySpace still dominates Facebook in one important respect—advertising. MySpace visitors viewed 31.8 million ads in April 2009, accounting for almost 47% of the total social network advertising space. Facebook was second, serving nearly 25 million ads and making up about 37% of the sector.
MySpace also led the revenue category, predicted to earn $495 million in 2009, 115% more than its rival.
