The term '#Adpocalypse' refers to a series of events on YouTube starting around 2017 where major brands withdrew advertising after their ads appeared next to controversial or extremist content. This led to massive shifts in YouTube’s monetization policies, resulting in widespread demonetization for thousands of creators. The meme encapsulates the panic, frustration, and irony of the situation, often depicting advertisers as oversensitive giants and creators as helpless victims of the 'yellow dollar sign.' It remains a staple in internet culture for discussing corporate censorship, platform instability, and the precarious nature of the creator economy.
