According to Business Insider, "Netflix and YouTube rule the daily video consumption of teens, according to a new survey by Piper Jaffray. Cable TV has seen a stark decline since 2015, almost being cut in half in terms of time spent by teens. This means that about 70% of teen video consumption isn't served by the traditional TV ad market." In fact there is such a vast disparity that teenagers watch twice as much Netflix as they do TV. What's even crazier is they've actually been watching Youtube.
