WhatsApp is a cross-platform messaging app that allows sending text messages, images, and audio or video files.
The company was founded by Brian Acton and Jan Koum in 2009. The app is free to use during the first year after installing, and at the start of the second year a user has to pay a small fee of $0.99 per year.
In March 2015, the app delivered about 50 bn messages. Experts believe that the messaging app has set off the destruction of traditional SMS, just like Skype once got its foot over the throat of international telephony. A curious fact is that the app’s fast expansion made mobile operators lose several dozens of billions of dollars.
According to the data from Apple, the WhatsApp application is the messaging app #1 in 121 countries of the world. In March 2015, the number of its users reached 1 billion.
