Facebook to monetize Messenger?

Kara Swisher of Re/code believes that the move is a clear signal from Facebook Inc (NASDAQ:FB) that it is preparing to monetize its Messenger product. Some have been speculating for a while that the social network will make it possible to attach money to messages sent through it, although Swisher says there are other ways for Facebook to monetize its messaging product.

Facebook Inc (NASDAQ:FB) said it processes 12 billion messages through Messenger every day. The social network has 200 million monthly active users on the app, which is both integrated into Facebook itself and can also be used separately. You may remember that Facebook Inc (NASDAQ:FB) recently acquired WhatsApp, but that will continue to run separately from Messenger, so Marcus will not be in charge of that.
