Facebook Buys Whatsapp for $19 Billion

Facebook Inc. agreed to buy messaging company WhatsApp for $19 billion in cash and stock.
The 55-employee company, which acts as a kind of replacement for text messaging, has seen its use more than double in the past nine months to 450 million monthly users. That makes its service more popular than Twitter Inc., the widely used microblogging service which has about 240 million users and is currently valued at about $30 billion.
