WhatsApp has announced its 250 million monthly active users, according to The Wall Street Journal.
WhatsApp launched 4 years ago and spends no money marketing itself. WhatsApp thinks the big reason of the popularity of their app is that they allow their users to message one another without paying high fees for text messages. The App is available for the iPhone, Android devices, BlackBerry and Windows Phone among others.
“WhatsApp’s growth is of concern to many other companies. That includes telecom carriers that make huge profits billing for text messages as well as Facebook FB -2.49% whose traffic relies in part on users trading messages with one another”, said The Wall Street Journal in the article.
