Unus Annus

Unus Annus was a YouTube channel created by Ethan Nestor and Markiplier. The two did a variety of activities on the channel, uploading one episode per day, while steering clear of normal gaming videos they are known for. Ethan represented the "Unus" persona, while Mark represented the "Annus" persona. 
The channel was created on November 15, 2019 as a way of giving their viewers a once in a lifetime experience, free of, what they considered as, restrictive guidelines, with the end-goal being to remove all of its content off of YouTube after a one year run without any intent of preserving it, as well as discontinuing Unus Annus' merchandise, hence the channel's name, which translates to "one year" in Latin. This method aligned with Mark's idea of not everything being immortalized on the internet and that the most treasured experiences lie within those unique, fleeting moments, tying into Unus Annus' symbolic imagery of frailty and death, and their commonly used term "memento mori" (Latin expression for "remember that you have to die").
Mark also stated that he would be issuing copyright takedowns to any re-uploads of his deleted content without his permission. On November 13, 2020, after a twelve-hour livestream, Mark and Ethan deleted all of Unus Annus' social accounts and finished off the broadcast by terminating the channel. A day after the channel was deleted, Mark and Ethan created post-mortem videos where they talked about their thoughts and feelings on the project.
Now that the channel has been deleted, none of the channel's content will be re-uploaded on their own channels and all of its associated merchandise will no longer be available for purchase. Hence, they suggested their viewers to create memories in their own unique experiences. Many have since suspected that the channel's true purpose seems to have been an experiment in how far YouTube's Community Guidelines could be pushed.
There are many archives online, due to the fact that they publicly stated that they had always planned to delete the channel. Some believe that archived videos on YouTube will be targeted with copyright takedown requests. Mark has stated that edited clips of Unus Annus' videos would be allowed, however full unedited archives would get taken down. The channel had 4.58 million subscribers and 867 million views before the channel was officially deleted. https://socialblade.com/youtube/channel/UCIcgBZ9hEJxHv6r_jDYOMqg 
==History==
Three days after its initial launch, Markiplier and Ethan uploaded a video on the same day with the same title, "This Will End in One Year".https://www.youtube.com/playlist?list=PLu1KhoiSiZF-ekaGk133VEnFEIO5YUj-2 Both videos have them explaining their new channel in a monotonous voice and a formal look. To promote their channel, Markiplier changed his profile picture to a blank white, while Ethan changed his to a blank black. After two days of having those profile pictures, they changed it back to their own ones.
In the one year that Unus Annus had existed on YouTube, it was a smash hit success. Unus Annus, up until its last day before its deletion, would have around 4.5 million subscribers. Every video uploaded would earn somewhere within the million view range, adding up close to 365 million views for the channel in total. This type of success goes far beyond the already established success for both the creators' main channels. The uploads were primarily vlog-like videos that were funny, philosophical, kind of disgusting and yet utterly wholesome. Some videos even had hidden codes or messages within them, like hidden sheet music on a black screen.
Other videos ranged anywhere from the two of them seeing how many slaps it would take to cook a chicken to having a "Pee Sauna." Other videos were dangerous, either thematically or literally, like when they tried to start an indoor fire to make smores or when Mark broke his nose. Unus Annus content was not a reflection of Markiplier or Ethan content, nor was it even distantly related to these gaming channels aside from links in video descriptions.
Both creators played characters that were not themselves, with Ethan being Unus and Mark being Annus. They wore black and white clothing, respectively, which helped to establish a balance between the two characters' unique personalities, as well as emulate the theme of hypnosis and dreaming. These characters would often frequently question life's meaning (or lack thereof) in the videos. They also occasionally die or have their deaths implied, allowing them to have characters who can die while the creators' main channels remain unaffected.
The channel was deleted at exactly 12:00 AM PST on November 14, 2020, following the other social media accounts for Unus Annus being privatized in the hour prior. The channel had 4.58 million subscribers at the time of its deletion and reached a peak of 1.6 million viewers watching the final livestream.
Although the original channel has now been deleted, there are many archives online. Mark has stated that edited clips of Unus Annus's videos would be allowed, however full unedited archives would get taken down. Despite this, many archive channels have persisted after the deletion of Unus Annus, much to Mark and Ethan's concern. They have pledged to take down those channels, which they have. However, there are so many, that many believe Mark and Ethan will have trouble keeping up.
On November 14, 2021, 1 year since the channel's deletion, Mark and Ethan made their respective videos (both named "Memento Mori"), where they visit the coffin (which is placed somewhere in a forest), and give their message what they felt about Unus Annus and the aftermath after the deletion.https://www.youtube.com/watch?v=twvf_OsOo-ohttps://www.youtube.com/watch?v=Ib1prHD6Wks Many of the Unus Annus fans made tribute videos to commemorate the anniversary.

==Norbert Moses==
Norbert Moses was a channel that Mark and Ethan created to attempt to beat the world record of getting to one million subscribers the fastest which was done in a day. The record wasn’t beaten, and the channel was deleted on April 18, 2020.
==Responses to archives/reuploads==
In mid-November 2020, DMCA claims were sent by Mark to 2+ websites containing all Unus Annus videos. However, some have speculated that these are not Mark's claims, but a fan's claims.
It is unknown how many videos/channels of reuploads Mark and Ethan have taken down, but Ethan has reported that all of them are on their radars.
All Unus Annus videos are archived by the Internet Archive Project and have seen no change in months.

==Trivia==
*Their channel name "Unus Annus" is Latin for "One Year", which explains the channel's lifespan.
*Many fans have dubbed Unus Annus a cult as a running joke during the channel's lifespan. Mark and Ethan have jokingly denied this and see the humor in the claim.
**The claim is partially true, as a cult is defined as "great devotion to a person, idea, object, movement, or work" and Unus Annus has shown great devotion to the idea of Impermanence, as it is the fundamental basis for the channel.
*Many fans claim that they will reupload and archive the videos made by Unus Annus, despite going against Ethan's and Mark's wishes.
**Markiplier replies to these claims saying that Unus Annus reuploads will be subjected to a copyright-strike and taken down by him.https://www.youtube.com/watch?v=Y8fJ2qpvJ2I
*The video titled "The Deep End of Omegle: Risky Boogaloo" was the only video removed from the channel before the channel was deleted.
*Some people who aren't a member of the Unus Annus channel but have collaborated on it are:
**jacksepticeyehttps://www.youtube.com/watch?v=14eE_ondcH8
**James Charleshttps://youtu.be/a7TY4h2u-Ps
*The first and last words said on the channel were both said by Ethan.
**The channel’s, as well as Ethan’s, first words were “We live our lives taking each second for granted.”
**Mark’s first words were “But what would you do if you knew how much time you had left?”
**Both Mark, Ethan, and the channel’s final words were “See you on the other side.”
*Mark and Ethan showed the viewers what was inside the coffin after hitting 1 million likes on the livestream.
*Fans were upset before the final livestream, as they believed the channel was set to end on November 15, 2020 and was being deleted a day early, but due to the leap year it was correct to end on November 14, 2020 as the channel only intended to be around for the normal 365 days, not the leap year's 366 days.
*In March 2022, Mark and Ethan appeared on GameGrumps's 10 Minute Power Hour under the collective pseudonym of "Unus Annus".Uno Anus (feat. Unus Annus) - 10 Minute Power Hour The episode name is even a pun on the name, using the card game in the place of Unus, and the word "Anus" in the place of Annus (though the latter existed before as a inside joke in the Unus Annus community).
