Digital influencers have several starring roles in a video YouTube put together highlighting people involved in the site’s most popular videos of 2015.
The video, titled YouTube Rewind 2015, includes: Bethany Mota, who makes beauty and fashion videos and has participated in video advertising campaigns with companies such as Forever 21 and JC Penny; Todrick Hall who has worked with Fiat; Joey Graceffa, who has helped to promote brands like Top Shop, Procter & Gamble, Intel, and eBay; and Miranda Sings, who has worked with brands such as Hallmark.
Celebrities such as John Oliver and James Corden also have cameos.

#YouTubeRewind was the number one trending topic on Twitter on Wednesday.
