MySpace is still the most popular social-networking site in the world but Facebook is growing the fastest, according to research from ComScore.
Since June last year, the number of unique users of Facebook has grown by 270 per cent.
However, with 52 million unique visitors, it still lags behind MySpace, which boasts more than twice as many at 144 million and is growing at a rate of 72 per cent. (Facebook growth outstrips MySpace, by Ben Camm-Jones)
