Social notworking site Facebook has overtaken Google as the site that most US people visit. Research outfit Hitwise said that the two sites accounted for 14 per cent of all US internet visits last week. Facebook’s home page recorded 7.07 per cent of traffic and Google’s 7.03 per cent.

The lead may be slim, but given the fact that most people visit Google regularly to work the world wide wibble, it is somewhat surprising. Facebook’s membership has more than doubled in the past year, passing the 200m mark in the middle of last year. It doubled this figure in February.

Facebook is only beginning to cash in on its success. Revenues at the social media company are estimated to be in the range of $1bn to $1.5bn this year, while Google took in $23.7bn last year.
