Portal sites lose ad dollars to Facebook

August 10, 2007

Social networking sites are benefitting from an increase in ad dollars knocking at their doors; in many cases, budgets set aside for portal sites are being transferred to network sites instead.  MySpace and Facebook represent 72% of social network advertising in the US.  Facebook has climbed to 31 million users, from 8.9 million a year ago.  By 2011 it is estimated that $2.5 billion a year will be spent on social network site advertising. eMarketer
