WhatsApp has a message for its users -- a lot of them.
The mobile messaging service announced today that it set a WhatsApp record on New Year's Eve, processing 18 billion messages on the last day of the year. The company said it delivered 7 billion inbound messages and 11 billion outbound messages, surpassing its previous record of 10 billion messages processed in one day back in August.
On Dec 31st we had a new record day: 7B msgs inbound, 11B msgs outbound = 18 billion total messages processed in one day! Happy 2013!!!-- WhatsApp Inc. (@WhatsApp) January 2, 2013
In comparison, Apple revealed in October that its iMessage text service had delivered about 300 billion texts sent by iOS users during the previous 12 months -- an average of less than a billion a day.
That kind of growth reportedly attracted acquisition interest from Facebook -- a TechCrunch report that the company called "a rumor and not factually accurate."
Founded in 2009, the Santa Clara, Calif.-based company provides a smartphone app for Android, BlackBerry, iOS, Symbian, and Windows Phone that delivers text messages, as well as images and audio and video messages.
