Messenger Rooms is Facebook's approach to online video-conferencing, though it's definitely targeted towards casual hangouts much more than business meetings. The service makes it easy to create video meetups with people who aren't necessarily in your friend list while keeping the group's creator in control. After coming to WhatsApp and Facebook's Portal screens, the company has announced that it will enhance the group calling feature in its Messenger apps with improvements to Room creation and discoverability. The developers are also working on custom backgrounds.
