Google's social network now has 90 million users worldwide in just four months since launch.
According to the company, as noted by "unofficial statistician" Paul Allen, 60 per cent of Google+ users are active on a daily basis, and 80 per cent active on a weekly basis.
During the quarter ended December 31, net profit at the company was $2.71 billion, with sales of $10.58 billion. Full year profits were $9.7 billion with sales of $37.9 billion.
"Google had a really strong quarter ending a great year. Full year revenue was up 29%, and our quarterly revenue blew past the $10 billion mark for the first time," commented Larry Page, Google CEO.
"I am super excited about the growth of Android, Gmail, and Google+, which now has 90 million users globally - well over double what I announced just three months ago. By building a meaningful relationship with our users through Google+ we will create amazing experiences across our services."
