Over the last two decades there have been many social network sites but none has achieved the level of market penetration achieved by Facebook. The social network site continues to grow at a rapid pace and revealed that for the first time, it had an active userbase of 1 billion people a day on average in September! That's 17 percent more than a year ago. Facebook also revealed that close to 1.6 billion people used Facebook at least monthly.
The company said its daily active users worldwide reached an average of 1 billion in September, 17% more than a year ago and the first time the closely watched metric notched that level. Almost 1.6 billion people used Facebook at least monthly, the company said.
Facebook has been growing both by adding more users around the world and by charging more for advertisements, especially video ads. CEO Mark Zuckerberg said more than 500 million people watch an average of 8 billion videos per day on Facebook. More than 400 million people per month are using Facebook's photo sharing service Instagram, over 700 million use the company's Messenger app monthly and 900 million use the Whatsapp service, Zuckerberg said.
