Facebook Tops 1 Billion Active Users

A million users isn’t cool. You know what’s cool? A billion users. Facebook announced that it had topped one billion active users, meaning users who visited the site within a month.

Although a few companies can claim to have had more than a billion customers, Facebook is the first social network to hit that number. Mark Zuckerberg, Facebook’s chief executive and founder, made the announcement in a blog post on the company’s Web site. “If you’re reading this: thank you for giving me and my little team the honor of serving you,” Zuckerberg wrote. “Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life.”

People have used the “Like” button more than 1.1 trillion times since it was added in February 2009. There have been more than 140 billion friend connections. And since the fall of 2005, nearly 220 billion photos have been uploaded to the site. Facebook also said it has 600 million mobile users.
