All told, the top 10 videos on YouTube this year had a collective 550 million views for a combined 25 million hours of time spent watching. Adele's Carpool Karaoke naturally topped the list with nearly 136 million views alone, followed by latecomer Pen-Pineapple-Apple-Pen with 95 million and homegrown curiosity channel What's Inside? with nearly 60 million views on its "What's Inside a Rattlesnake Rattle?" video.

Also new this year: YouTube filmed a couple of the Rewind 2016 scenes in 360 video as a dizzying Easter Egg for the superfans.
