Vine is a short-form video sharing service. Founded in June 2012, it was acquired by microblogging website Twitter in October 2012, just prior to its official launch. The service allows users to record and edit five to six-second long looping video clips, and to "revine", or share others' posts with followers. Some Vines are revined automatically based on what is popular. The videos can then be published through Vine's social network and shared on other services such as Facebook and Twitter. Vine's app can also be used to browse through videos posted by other users, along with groups of videos by theme, and trending videos.
