Have you heard of WhatsApp?
It's a fantastic app that lets you send and receive text and pictures messages for free, along with videos and voice notes and even a group chats! Better yet, it's not just limited to the iPhone and Android. It's available for Windows phones too! Maybe that's why more than 450 million people use it each month.
So it comes as no surprise that Facebook wanted to get in on the action. The company announced it purchased WhatsApp for nearly $16 billion - $4 billion cash and $12 billion worth of Facebook stock shares.
