The phrase became famous during the PewDiePie vs T-Series subscriber race in late 2018 and 2019, when fans promoted Swedish creator Felix Kjellberg to keep his channel ahead of the Indian music label. Supporters repeated subscribe to PewDiePie on videos, signs, and social posts, turning a simple slogan into a widespread internet campaign. The clip survives as a short reminder of that era, still dropped into edits long after the race ended as a nostalgic meme reference.
