The Internet Historian Plagiarism Accusations gained massive traction following a nearly four-hour video essay by YouTuber Hbomberguy titled 'Plagiarism and You(Tube).' The video revealed that Internet Historian's popular 'The Cave' video was almost entirely copied from a Mental Floss article by Lucas Reilly. The discovery led to 'The Cave' being removed and re-uploaded with changes, sparking a wave of memes across Reddit, Twitter, and YouTube. These memes typically mock the irony of a 'historian' failing to cite sources or use the IH avatar in situations involving stolen work. It serves as a commentary on content originality and the downfall of high-profile internet personalities when confronted with evidence of intellectual property theft.
