Facebook CEO Mark Zuckerberg announced that the social network now sees 2 billion people using the platform each month. Facebook is marking the milestone with a new Good Adds Up campaign launching one day after the Messenger team announced new enhancements coming to the app.

Zuckerberg announced Facebook’s milestone in a post today:

Facebook added that the 2 billion people number refers to “people connecting and building communities on Facebook every month.”

We’re making progress connecting the world, and now let’s bring the world closer together.

It’s an honor to be on this journey with you.

To mark crossing the 2 billion monthly users milestone, Facebook is kicking off a Good Adds Up campaign at facebook.com/goodaddsup and in the News Feed that will include “a personalized video to celebrate bringing the world closer together.”

Facebook will also start thanking users for sending Love reactions, happy birthday wishes, and creating groups as part of the milestone celebration. For comparison, Facebook-owned Instagram hit 700 million monthly users back in April.

Separately, Facebook’s Messenger team has detailed new video chat features coming to the service.

Facebook and Messenger are available for free on the App Store.
