WhatsApp is an instant messenger or instant messaging system between users using the Internet. Allows you to send text messages, various kinds of images, audio and video recordings, etc.It is supported by many platforms, including such popular ones as Android, Windows Mobile, Nokia Symbian, iOS, Windows, etc.
The first launch of the application took place back in 2009. It is alleged that by April 2012, WhatsApp users sent more than 2 billion messages daily, and by August of that year this figure reached 10 billion.
Unfortunately, the exact number of WhatsApp users was not disclosed, but according to some reports, in the spring of 2016, more than 1 billion users used the application! Agree, the figure is impressive.
It is believed that the emergence of instant messengers like WhatsApp or Viber app has extremely negatively impacted the profits of mobile carriers around the world. So, their loss due to the fact that users are increasingly using SMS messages is tens or even hundreds of billions of US dollars. However, telecom operators began offering tariff packages with mobile traffic, which partially offset the loss of funds.

In early 2014, WhatsApp was acquired by Facebook for an astronomical amount of $ 19 billion. At the same time, only 4 billion were transferred in cash, another 12 billion were transferred by Facebook shares, and the remaining 3 billion by WhatsApp founders and employees should have been received within 4 years from the date the transaction was closed.
