Facebook keeps getting bigger.
The social-media giant says it now has 1.55 billion monthly active users, a 14 percent jump from a year ago. Of these, 1.39 billion accessed the service through mobile devices. The raw numbers mean that more than 1 out of every 5 people on the planet log in and use Facebook at least once a month. (Facebook now averages just over 1 billion users a day.)
The latest user metrics were revealed in Facebook's quarterly earnings report posted Wednesday. The company reported a better-than-expected 40.5 percent jump in quarterly revenue helped by the launch of new advertisement services and updates to its mobile app, which drove more ad sales.
"We had a good quarter and got a lot done," Mark Zuckerberg, Facebook founder and CEO, said in a statement. "We're focused on innovating and investing for the long term to serve our community and connect the entire world."
Facebook posted third-quarter earnings of 57 cents per share on $4.5 billion in revenue. Ad revenue — the vast majority of Facebook's sales — jumped 45 percent to $4.3 billion. Mobile ad revenue accounted for 78 percent of that, up from 66 percent in the prior year.
"We think we have the best mobile ad product in the market. We're able to target, we're able to measure. We have broad scale," Chief Operating Officer Sheryl Sandberg told CNBC.
Facebook is seeing a lot of growth in video. Zuckerberg said Facebook now serves more than 8 billion videos every day, which are being consumed by more than 500 million users.
