Markiplier (Mark) and CrankGamePlays (Ethan) joined forces on November 12, 2019 to launch an experimental YouTube channel that would last one year, essentially as a loosely scripted variety show with the overarching message to "live life to the fullest, because time is running out. Described as part art project part insanity, it is coming to an end. On November 13th, 2020, the Unnus Annus channel will be deleted and that will be that. If you haven't checked it out yet, as of this writing anyway, your chance to do so is running out.
