OnisionArchive
OnisionArchive, or Archive, is one of Greg's active YouTube channels. Archive was always one of his least popular channels.
Origin
Greg created then channel on December 03, 2008. He would upload bloopers, clips, and videos that he removed from his comedy sketch channel as well as his serious Speaks channel.
Today
Greg now uses the channel to immediately re-upload videos he deleted from his UhOhBro and Speaks channels. In 2013 Greg described this as: "Where all classic Onision videos come to live out the rest of their lives :)" (Source)
Many believe he does this to squeeze out more views and ad-revenue from videos whose view count plateaued. It is is also rumored that when Greg receives backlash from people whose pictures he used in a video, he will move the video to his Archive channel to get them off his trail. Although, any instance of this happening could have just been a coincidence since he moves videos to the channel quite frequently.
