Vine was founded in 2012 and in just a few short months was acquired by Twitter after becoming immensely popular with teens and young adults. Created by Dom Hofmann, Rus Yusupov, and Colin Kroll, it allowed users to create short videos up to six seconds long. In January 2013 it was launched on iOS, followed a few months later by the Android and Windows Phone version. It quickly became the most used video sharing app and was soon the number one most downloaded free app in the Apple App Store. Vine Kids was launched in 2015, in direct response to criticism on how pornography was handled, which lead to the app being rated for 17+ users by Apple.
