Facebook's Messenger service has been naturally integrated into its social media platform allowing users to quickly instant message other users they are friends with. Group conversations can be used for small teams to communicate and video calling is available as well. In April of 2020, Facebook announced a new feature for Messenger called Rooms. Rooms is a feature that provides video conferencing experiences for groups up to 50 callers. Facebook's video conferencing solutions also provide simple screen sharing, audio/video controls, and meeting layout formats. Until April of 2020, Facebook's main focus in the video communications space has been one-way live streaming. After a 2016 launch, Facebook’s dominance in the live content delivery market has been rivaled only by Google’s YouTube and Amazon’s Twitch platform. Facebook developed several innovative features for live and on-demand video such as watch parties and interactive live audience polling. In 2017, the company's founder Mark Zuckerberg called video a “mega-trend” which would be on par with the move to mobile. Zuckerberg has also said Facebook would become a “video first” company in many subsequent interviews.
