The NPC Craze, also known as NPC Streaming, is a digital phenomenon that emerged on TikTok in 2023. It involves users, known as streamers, pretending to be non-player characters (NPCs) from video games and acting out repetitive phrases and actions for hours on end. Viewers can send them gifts, and some streamers have even made a fortune from this activity. The term "NPC" stands for "non-player character," which refers to the characters in video games that are controlled by the games artificial intelligence rather than by a human player.
