The most recent data from the Google Play Store, the top downloaded messaging app in the USA, is WhatsApp Messenger. Given that it has two billion users worldwide and is the most popular messaging app, this is hardly surprising.  Snapchat is the second-most popular communication app in the USA, right behind WhatsApp. In addition, WhatsApp and Snapchat are two of the USA's most popular social media sites. This is because they permit users to exchange and share photographs and videos in addition to text messages.  The messenger comes in the third position after this. With almost 550 million monthly active users, Telegram is the fourth most widely used messaging app in the USA.
