The events of March 2019 in Christchurch, New Zealand, represent a significant and tragic moment in contemporary history that highlighted the complex relationship between internet subcultures and real-world violence. The perpetrator's intentional use of viral media tactics, including the use of specific slogans and a live-streamed format, was designed to exploit the mechanics of the internet to gain notoriety. This event led to profound changes in international social media policies, the creation of the Christchurch Call, and a global conversation regarding the responsibility of tech platforms in moderating extremist content. It remains a focal point for researchers studying the weaponization of digital memes and the evolution of online extremism in the 21st century.
