If the latest rumors are correct, Google is looking at acquiring WhatsApp in a deal that could be worth around $1 billion. The deal reportedly started out four or five weeks ago, where Digital Trends' source said that WhatsApp is "playing hardball" and are pushing for a higher acquisition price. This price is being pushed "close to" $1 billion right now.
With WhatsApp's immense popularity, and Google's soon big push into a possible unified messaging system - acquiring WhatsApp might be yet another smart billion-dollar acquisition by Google. We should hear more about this in the coming weeks.
