When was the last time some, crazy, random, extremely well produced, content like "Kung Fury" happened?

If you're forced to watch ads to watch the video, it's not free unless your time is worthless. Although, ads on YouTube videos can be circumvented. Thereby practically free.

Someone is paying for it, just because it's not you doesn't mean it not paid for. Thats why youtube has fifty bajillion ads and everyone has sponsorships these days.
