Facebook bought WhatsApp for 20 Billion dollars.
The service sends billions of messages each day, and they're still not making money from it.
When acquired WhatsApp in 2014, CEO Mark Zuckerberg set a threshold for when the social network would begin seriously thinking about monetizing the popular messaging platform: 1 billion users. That was more than double the 450 million monthly active users (MAUs) that WhatsApp had at the time of acquisition. It's now been just over a year since WhatsApp hit the 10-digit threshold, but investors still have yet to see any semblance of financial results from the acquisition.
