Steve Bannon dumped a huge chunk of change into YouTube to fuel Gamergate. He talked about radicalizing young men through the internet way back in like 2009. The Kochs followed his example, pumping more traditional media personalities (Charlie Kirk, Ben Shapiro, etc.) full of cash on YouTube, Facebook, and other social media sites.

It's no coincidence YouTube was mostly cat videos, video game compilations, music, and sketch comedy for a long-ass time, then there were hundreds of rightwing grifters practically overnight doing 4 hour rants about Zoey Quinn.
