Move over Facebook || WhatsApp, from free texting to social network of its own
Over 25 billion messages are sent daily on the popular application, but advertisers are having trouble cutting off a slice of the action.
WhatsApp, the smartphone app that started as a nice, free application for text messages has become a social network on its own, thanks to the function that allows users to define their own chat groups. Close-knit groups of friends and relatives stay active all the time, and provide updates in real time. Everyone is there, from cousins, to classmates to groups from the workplace and the neighborhood.
