Yahoo Finance WhatsApp's Record 64bn Messages In 24 Hours
WhatsApp has handled a record 64 billion messages in just 24 hours, just a few weeks after the company was bought by Facebook (NasdaqGS: FB - news) .
Some 20 billion messages went outbound, while 44 billion messages were received.
That works out at around 750,000 messages handled by the company every second.
It is unclear which specific 24-hour period the figures relate to.
The outbound and inbound figures do not match because messages sent to multiple contacts are only counted as one outgoing message.
Chief executive Jan Koum recently said the company had more than 200 million active monthly users.
By comparison, BlackBerry Messenger has 60 million users who send and receive around 10 billion messages each day.
Korea's KakaoTalk claims 96 million registered users, who send 5.2 billion messages between them per day.
WhatsApp was bought by Facebook in February for $19bn (£11.4bn), and just days later it suffered an outage.
It also came under scrutiny for privacy issues, prompting some analysts to speculate on whether it could continue its rapid growth.
The record announcement was made on WhatsApp's Facebook account, and is more than double the 27 billion message tally for June.
Its previous best was 18 billion on December 31 2012.
The messaging app allows users to send free text and multimedia messages to individuals or groups.
It is available on iOS, Android, Windows Phone, BlackBerry (Berlin: RI1.BE - news) , Asha, Symbian and others.
The app is due to add voice calls in the next few months.
