NPC streaming is an online phenomenon that has gained popularity on TikTok. In NPC streaming, creators act like non-playable characters (NPCs) from video games, repeating set phrases and movements as if they have been pre-programmed. During TikTok livestreams, the phrases and movements the "character" reacts with come from virtual gifts, which viewers can purchase and send to creators as they stream. The trend has been described as having a robotic quality, with creators emulating the repetitive actions and dialogue of NPCs. The trend has been criticized for containing sexual undertones, but some creators and viewers enjoy the fast pace of the videos and the gratification they feel from controlling the human NPCs on-camera reactions in real time. NPC streaming can be lucrative, with top practitioners earning thousands of dollars per day.
