Video will account for 80% of all internet traffic by 2019, up from 64% in 2014, says technology giant Cisco. Facebook founder Mark Zuckerberg says that 90% of the social network's content will be video-based by 2018. And network company Ericsson thinks mobile video traffic will rocket 55% a year between now and 2020. So how should businesses be responding to this new video world and what technologies are out there to help them? Developments in data-driven marketing and virtual reality (VR) will be among the major game-changers in the coming year and beyond, some observers believe. VR devices such as Google Cardboard, which can be bought for as little as $10 (£7), could be given away by companies to clients to view their videos. Samsung is bundling the Oculus Gear VR headset with its new Galaxy S7 smartphone.
