 ## WhatsApp's rise
 
-For those unfamiliar, WhatsApp is a tool that makes it convenient and easy to help Facebook further its core mission: the optimization and auctioning of human behavior (colloquially known as "targeted advertising"). It originally persuaded people to consent to this by allowing them to send text to each other over the Internet, something that was already possible (see the following link), and combining an easy-to-learn UI with successful marketing. It then expanded to include features such as voice and video calls.

 Having its own proprietary chat system incompatible with other clients allowed WhatsApp to build a [network effect](https://en.wikipedia.org/wiki/Network_effect): WhatsApp's existing users were held captive by the fact that leaving WhatsApp meant losing the ability to communicate with WhatsApp users. People switching from WhatsApp must convince all their friends to switch, too; this includes less technically inclined friends who had a hard time learning WhatsApp in the first place.
