TV is no longer just a box in the living room. Unless you haven't been paying attention, you know it also includes smartphones and tablets, and a new report from video services company Ooyala provides more evidence of that trend. By analyzing viewing data from 200 million people, the Global Video Index report found mobile and tablet viewing increased 719% from 2011 to 2013. In 2013 alone, the share of videos watched on mobile phones increased by 10 times. The holiday season played a role in these shifting viewing habits. Not only were consumers watching product videos to learn about potential gifts, but many also received tablets and smartphones as presents, helping drive growth in December. Overall, mobile phones and tablets accounted for 26% of viewing by the end of December of 2013, up from 18% in October.
