At the end of June, Mark Zuckerberg announced that Facebook had hit a new level: two billion monthly active users. That number, the company’s preferred ‘metric’ when measuring its own size, means two billion different people used Facebook in the preceding month. It is hard to grasp just how extraordinary that is. Bear in mind that thefacebook – its original name – was launched exclusively for Harvard students in 2004. No human enterprise, no new technology or utility or service, has ever been adopted so widely so quickly. The speed of uptake far exceeds that of the internet itself, let alone ancient technologies such as television or cinema or radio.
Also amazing: as Facebook has grown, its users’ reliance on it has also grown. The increase in numbers is not, as one might expect, accompanied by a lower level of engagement. More does not mean worse – or worse, at least, from Facebook’s point of view. On the contrary. In the far distant days of October 2012, when Facebook hit one billion users, 55 per cent of them were using it every day. At two billion, 66 per cent are. Its user base is growing at 18 per cent a year – which you’d have thought impossible for a business already so enormous. Facebook’s biggest rival for logged-in users is YouTube, owned by its deadly rival Alphabet (the company formerly known as Google), in second place with 1.5 billion monthly users. Three of the next four biggest apps, or services, or whatever one wants to call them, are WhatsApp, Messenger and Instagram, with 1.2 billion, 1.2 billion, and 700 million users respectively (the Chinese app WeChat is the other one, with 889 million). Those three entities have something in common: they are all owned by Facebook. No wonder the company is the fifth most valuable in the world, with a market capitalisation of $445 billion.
