New figures from metrics firm comScore show that, in May, the battle of the social-networking sites may have gained a new front-runner: Facebook appears to have surpassed long-time rival MySpace in worldwide unique visitors for the first time. ComScore representatives said that Facebook's lead began in April, when the site passed MySpace by a hair, and widened in May. Facebook, according to comScore, pulled in 123.9 million unique visitors in the month of May, beating MySpace's 114.6 million, and 50.6 billion page views, compared to MySpace's 45.4 billion.
