Twitter has finally begun testing autoplay videos in user timelines. But they’re reportedly working on a small percentage of the user base at the moment. Except for Vine videos, all videos will start autoplaying, including video ads. Facebook began autoplaying videos about a year and a half ago and that boosted video uploads and consumption on the social network. It looks like Twitter is hoping to replicate that. There’s no word yet when the widespread rollout will happen. Watch your timeline though. You should be seeing more animated tweets soon.
