Instagram just got finished showing off its new video features at the big “Facebook event,” and brands are already using it for marketing purposes.

There will no doubt be plenty of this from brands very soon, especially given the stats Instagram dropped at the event. The company noted that it has 130 million monthly active users, and that it has seen 16 billion photos shared. It also sees a billion likes per day.

Update: Business Insider has now put out an article showing that Urban Outfitters and Burberry have also started using Instagram Video.
