The age of videos that play automatically is upon us. First it was Vine, then it was Instagram, and now Facebook's getting in the mix. A new update for the company's iOS app adds the feature, which will play videos automatically. So far that's limited to videos on profiles, verified people pages, and band pages. Facebook also isn't auto-playing videos from outside video hosts like YouTube. Before grabbing your pitchfork to storm Facebook's headquarters over slurping all your mobile data bandwidth, the feature can be set to work only over Wi-Fi, something that can be toggled in Facebook's settings. Facebook has confirmed to The Verge, however, that users won't be able to turn the feature off completely.
