This year, did you share a Waleed Aly viral video? Dabble in Instagram stories or watch the PM do a Facebook live? 2016 was the year we filmed everything. So what were the big hits? What makes a video go viral? And do we really need to see Snapchat Birth? With more people watching Kylie Jenner's pouty Snapchat every day than Australia's biggest ratings shows of all time, umm, yeah. There are no signs of it letting up.
