In 2013, Mitch Grassi and Scott Hoying of the Grammy award-winning a cappella group Pentatonix started YouTube channel SUPERFRUIT, posting comedic vlogs about pop culture, fashion, Wyatt the cat, and “Weekly Obsessions." Their videos sometimes feature YouTuber collaborations on a cappella mashups of “Hip Hop Goes Broadway," “Beyoncé," and “Frozen Medley." The channel’s popularity has created a celebrity and a following for Mitch and Scott independent of Pentatonix, with close to 2 million subscribers and more than 180 million views. Their #superfruitlivestream celebration of 1 million subscribers trended #1 in the US and worldwide at the time of the broadcast.
