Facebook CEO Mark Zuckerberg confirmed that the social networking site reached 1 billion active users worldwide yesterday. That’s good news for a company that's faced some recent setbacks, including a fairly disastrous IPO and some privacy concerns.
And despite the billion-user milestone, the growth has slowed somewhat recently. Last quarter, 57 million fewer people registered with Facebook than during the first three months of 2012.
But tonight's number offers some hope – 600 million. That's the number of people – more than half of that impressive 1 billion – who use the mobile version of the site. And according to new reports, the mobile ads are outperforming those on computers. As Zuckerberg himself has emphasized recently, that's likely where the future of the company lies.
