Watch is comprised of shows, a new type of video on Facebook. Shows are made up of episodes – live or recorded – that follow a consistent theme or storyline. Shows are a great format if you want to share a video series, like a weekly cooking show, a daily vlog, or a set of videos with recurring characters or themes.
