#UnusAnnus (Latin for “one year”) documented Markiplier and Ethan Nestor’s experimental YouTube channel (November 15, 2019 - November 13, 2020) posting daily videos for exactly one year before deletion. The hashtag tracked the death clock ticking down, final livestream with 1.5M viewers, and the project’s meditation on mortality and internet permanence.
The Concept
Every day for 365 days, a new video. Then complete channel deletion—no archives, no reuploads. #UnusAnnus captured the experiment’s philosophy: “Memento Mori” (remember death), appreciating fleeting moments, and challenging YouTube’s permanence culture. The black-and-white aesthetic and death clock imagery reinforced mortality themes.
Community Investment
As deletion approached, #UnusAnnus intensified. Fans treasured limited-time content, created memorial art, and planned watch parties for the finale. The project banned reuploads/archives—experiencing it required presence during that year. This artificial scarcity created FOMO-driven engagement but also genuine appreciation for impermanence.
The Deletion
November 13, 2020, 12 hours before death: a livestream showing entire channel deletion in real-time. #UnusAnnus tracked 1.5M concurrent viewers watching Mark and Ethan reminisce, cry, and press delete together at midnight. The channel, 4.56M subscribers and 800+ videos, vanished. Reuploaders violated the spirit, but the official archive died as planned—a rare internet moment that truly ended.
