On November 15, 2019, Fischbach launched a new channel with fellow YouTuber Ethan Nestor (formerly known online as CrankGameplays) called Unus Annus, a channel which planned to upload a video every day for one year, after which the channel would be deleted along with its videos. The channel rose to early success, gaining 1 million subscribers in its first 5 days and 4.56 million in its last few minutes, and over 11.5 million video views in its first week. Following a final 12-hour live stream that peaked at over 1.5 million concurrent viewers, the channel was deleted by Fischbach and Nestor on November 14, 2020, at 12:00 a.m. PST.
