Vine was acquired by Twitter in October 2012. The Vine app debuted in January 2013 and is currently available for free on the Apple App Store (iOS). Compatible devices include the iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, the third-, fourth- and fifth-generation iPod Touch, and the iPad. Vine requires iOS 5.0 or later and has been optimized for Apple's iPhone 5.
To use Vine, users open the app, aim the device's camera at a subject matter, then hold a finger on the screen to record. Lifting a finger off the screen pauses the video capture and allows users to change subject matters and film another clip. Vine automatically links recorded clips together, creating a unique, six-second video to be posted to users' Vine profiles and shared via Twitter and Facebook, with more social media options promised in the future.
Vine's newsfeed resembles those of Twitter and Instagram. As users scroll, six-second videos play in a looping fashion. From the newsfeed, users can share any video on Facebook or Twitter or embed videos on the Web.
Within the Vine app, users can view videos from their followers in their "Home" screen. Under the "Explore" tab, Vine users can view trending posts, editor's picks and featured or trending hashtags. Vine also allows users to view their recent activity, including new follows, comments and "likes," all on one screen.
Vine was founded by Dom Hofmann and Rus Yusupov in June 2012.
