CHICAGO: The number of internet users over the age of fifteen passed one billion in December, with Google's stable of websites receiving visits from 777.9 million of this audience over the month, reports online measurement firm comScore.

China contributed 180 million web users to the total, followed by the US with 16.2%, then Japan (6.0%), Germany (3.7%) and the UK (3.6%).

Home and business internet traffic was included in comScore's figures, but mobile internet, handheld devices and individuals using internet cafes to access the web were not counted.

Predicts comScore president/ceo Magid Abraham:  "The second billion will be online before we know it, and the third billion will arrive even faster than that, until we have a truly global network of interconnected people and ideas that transcend borders and cultural boundaries."
