Also scale on the supply side. It took time to get to a place where obviously the video should be on Youtube, and that's hard to replicate. This applies to the content which would exist anyway, and then doubly to content created for Youtube. Grand Pooh Bear would be on Twitch anyway, but it doesn't really make sense for a Tom Scott, let alone "Corrections" which is a Youtube-only addition to Seth Myers "Late Night" show. Likewise until it gets fairly "big" it doesn't make sense to officially put your music videos on Youtube. Today that's basically the main way they're getting seen.
