Originally created by cartoonist J.L. Westover for his webcomic Mr. Lovenstein, the 'Death Knocking on Doors' meme depicts the Grim Reaper walking down a hallway of blood-stained doors, representing things that have already 'died' or become obsolete. After passing three doors marked with past failures, Death knocks on a fourth door, signaling the next victim of cultural or technological irrelevance. It is widely used to mock dying software, social media platforms, or trends that are clearly on their way out. The meme effectively blends dark humor with social commentary on the lifecycle of brands and products in the digital age.
