As it relates to sponsorship transparency, I think platforms such as instagram, youtube, etc have broader issues with their influencers whether CGI'ed or not...

I did find it really interesting that a CGI character could be more appealing to brands as there is much more complete control over image, no past issues, etc.

Reminds me of Hatsune Miku, virtual pop singer in Japan. As CGI continues to improve, wouldn't be surprised if we start to see entire digital labels churning out multitudes of artists/bankds
