 Facebook is officially launching Watch Party, its new format for viewing video with a group, after about half a year of testing it. 

Watch Party, which lets people watch video together at the same time like a digital living room, is rolling out to all Facebook groups Wednesday. Facebook will also begin testing Watch Party for pages, which are basically profiles that belong to an organization or public figure instead of a mere-mortal individual. Facebook said it didn't have a timeline for when the feature would be available on regular profiles.
