I saw this yesterday, but had no idea he was related to Porter Robinson. That helps put a few things in perspective... a bit.
Either way, it's absolutely amazing he went all the way to japan to research a youtube video being deleted o.o.
Though it's interesting to note the theory at 2:12 sounds way off- iirc the miku x dominos campaign was SO popular they ran out of supplies extremely quickly, with far more demand than they had expected, and had to do a second run of the special boxes or something like that.
Good thing the likely answer turned out to be something way different (will refrain from mentioning it because it'd spoil the video!)
