The slack has been picked up by other networks. Tumblr, for example, with its small, easy-to-link posts with high graphics content; Snapchat, which deletes posts and photos after a few seconds; Instagram, which allows users to manipulate and share photos; and, of course, Twitter. But Mark Zuckerberg of Facebook has something most of these others don't: a war chest. And thus the purchase, for $1 billion last year, of Instagram. And now the mammoth $19-billion purchase of the instant messaging service WhatsApp. It's obvious, really, that Facebook is not paying for extra-special technology in buying WhatsApp. Other such SMS replacement services exist. Viber dominates West Asia, and was recently bought for $900 million by a Japanese online retailer. China uses WeChat. Japan uses Line. Eastern Europe uses Telegram. WhatsApp, however, has the largest user base, and is big in Western Europe, Africa and South and Southeast Asia. And it's the only one that charges user fees; the others get money from advertising or value-added services. But Facebook probably isn't interested in the money that WhatsApp makes from its downloads. It is interested in WhatsApp's users: 450 million mobile users, about half of the number that uses Facebook's apps. And it's adding a million users daily.
Facebook wants those users. And so it paid for them - $19 billion, which comes to $42 (about Rs 2,600) a user. This is quite a lot; it's difficult to see how each WhatsApp user could eventually be worth that much to Facebook or its advertisers. When Viber was sold, its users were valued at $8.50 (about Rs 530) a user. Even if just the $4-billion cash portion of the Facebook-WhatsApp deal is examined, then Facebook paid more than that. And it's clear why: Facebook is desperate. It can't afford to fall behind in terms of dominating the market - and demographics are against it. Rather than organically growing its network with younger users, it needs to capture them outright - hence the purchase of WhatsApp. It's betting that smart integration of the two networks will follow and help it reverse its usage decline in the 13-21 age group. Facebook itself is 10 years old now; and it is spending money like water to stay young.
