Android is the most successful social video brand of 2015, according to video ad tech firm Unruly. As part of Unruly's Video Sharing Awards, the brands that have been shared most over the year have been ranked. All awards are based on the number of shares across Twitter, Facebook and the blogosphere that each brand has accumulated over the year. This way it measures a brand's viral success more accurately than using the number of views each video receives, which Unruly claims does not denote social success.
