I don't use YouTube on any streaming box or "smart" TV. I'm curious, how many people actually do that? (Honest question.)
There's a ton of quality content that's longer form and a huge amount of educational content. I regularly watch the Grantland channel's videos and Vice News has a good channel. John Oliver uploads segments of his HBO show Last Week Tonight. Same with many others' shows like Conan O'Brien, Kimmel, and Fallon. There's live and archived content from the NBA D-League. My current educational content is an 84 part CCNA training series recently produced and uploaded to YouTube. It's endless if you start looking into your own interests.
I think some people see YouTube as only the internet age equivalent of MTV, but it's so much more than that once you move beyond the landing page. I'm surprised anymore at the amount of people who don't realize how vast and content rich YouTube is.
