Facebook has overtaken rival social network MySpace for the first time - provoking an angry outburst from the man who paid $580m for MySpace only three years ago.
Facebook had 123m unique visitors in May, an increase of 162% on May 2007, according to the latest Comscore figures.
By contrast, MySpace drew 114.6m uniques, with visitors growing by only 5% since May 2007.
It's the first time Facebook has managed a significant lead over its chief rival, after the pair were almost level-pegging in Comscore's April figures.
The news hasn't gone down well with News Corp boss, Rupert Murdoch, whose company bought MySpace back in 2005. He claims Facebook has "done a great job of being flavour of the month the last six months of last year," but that Facebook isn't a real social network, claiming the site is "just a directory".
