Unus Annus (literally meaning One Year) is a Youtube channel run by Mark Fischbach (Markiplier) and Ethan Nestor (CrankGameplays). Their objective is to do interesting and unique things for one year until they delete their channel (alongside their videos) and stop selling merch.

The channel will be deleted in November 15 2020.
Unus Annus is so interesting. I always wanted to know what being pepper sprayed felt like.

A now dead channel featuring Mark Fischbach and Ethan Nestor with the purpose of deleting in a year's time. The channel was meant to showcase the idea that we as humans only have so much time, and that the clock on our lives is always ticking. The channel was light in content but usually had dark undertones of death and the inevitability that one day we will not be remembered. The idea of making the most of the time we have remaining in our lives was frequently brought up in videos, both subtly and subliminally. Unus and Annus, the two characters of the channel were the face of many conspiracy theories and lore regarding who they were, how they came to be and if they could stop the clock that counted down until the day they died, when the channel was deleted. The beginning and end of each video was displayed with a ticking timer counting down the days, hours, minutes and seconds of how much time the channel had left to live. Despite the begging of fans and friends alike, on November 13th, 2020 the Unus Annus youtube channel was deleted, along with its 365 videos, lore, characters, secret messages and mysteries never fully discovered. The channel is forever gone now, but the memory of Unus Annus lives on in the minds of fans and the 4 million subscribers that followed the channel to its death. The clock is ticking for us all, and one day we will die. Let us make the most of the time we have left. Memento Mori. Unus Annus.
Memento Mori. Unus Annus.
