In Short

Vine is a social video sharing service that is owned by Twitter. Vine allows users to create 6-second video clips and share them to the Vine service and/or Twitter. Working much in the same fashion as Twitter and Instagram, users can follow other Vine users to see their feed.

There is currently no Vine app available for BlackBerry, but some users have had mixed success using the Android version of the app. 

A native third-party Vine app is currently in the works for BlackBerry 10 users.
