Vine () was a short-form video hosting service where users shared six-second-long, looping video clips. It was founded in June 2012; American microblogging website Twitter acquired it in October 2012, before its launch on January 24, 2013. Videos were published through Vine's social network, and could be shared on other platforms such as Facebook and Twitter. The Vine app could be used to browse videos, along with groups of videos by theme, and "trending" videos. Vine competed with other social-media services such as Instagram and Mobli.
