Facebook Cartoon Profile Picture Week began as a viral social media movement, primarily gaining massive traction in late 2010. The campaign encouraged users to replace their profile photos with images of childhood cartoon characters, ostensibly to raise awareness for child abuse prevention or simply to celebrate collective nostalgia. While the movement saw millions of participants, it eventually became a subject of internet parody and criticism for being an early example of 'slacktivism'—where users feel they are contributing to a major cause through minimal effort. Today, the meme is frequently used to mock performative activism or to trigger a wave of early 2000s nostalgia among millennials who remember the original Facebook era.
