YouTube just released its annual video mashup that pays tribute to all the biggest viral moments and people of 2015.
You’ll see Left Shark, a handful of Shia Labeouf “Just do it” copycats, and cameos by people likeHeaven King and Bethany Mota. And people well-versed in internet culture and YouTube stars will recognize dozens of in-jokes and references that will fly right by those who aren’t.
YouTube culture exec Kevin Allocca tells Business Insider that shooting for the ~7 minute piece took 21 days across multiple cities around the US and the world.
“The sets have this fun party atmosphere,” he said. “Some of these [YouTube creators] are pretty huge stars who are busy with crazy schedules, so to have them in the same place is really fun.”
