Do you use WhatsApp to talk to your friends?
The free instant messaging app is used in 109 countries, or 55.6 percent of the world. But with no advertising in the app and no charge to use it, many people wonder how WhatsApp makes money.
In 2014, Facebook acquired WhatsApp for $19 billion.
In January 2016, Facebook revealed that WhatsApp was monetized in "a very limited fashion," and may not be making meaningful money in the long term. Executives also suggested that the strategy would change.
