Videos are watched on social media more than ever before, and live video has become one of the most engaging forms of content on Facebook, Instagram, Twitter and Twitch. In 2018 daily watch time for Facebook Live broadcasts has grown by more than 4x, and 1 in 5 Facebook videos is a Live broadcast. Closed captioning traditionally opened up videos to audiences who are deaf or hard of hearing. People who have their captioning settings turned on will then automatically see closed captions on Live broadcasts on mobile and desktop whenever they're available. Closed captioning is mandatory on live video streamed in the United States, but it is also a feature used by broadcasters worldwide.
