Those sponsor spots absolutely blow my mind. They're there, forever in the video no matter how times it's viewed. That's a lot of trust to have in an advertising relationship, both the creator (who is basically tattooing a person in a portrait they're painting with an ad) and company have to determine if it's enough compensation based on..... feels I guess lol. I'm pretty sure there is some after data but how do you know which videos take off or not? Then if there's any controversy, whole things a mess and I hope they get a lot for it.
