This chime comes from Samsung televisions sold around 2010 to 2012, where it played automatically during power-on. Clips of the startup were later uploaded to soundboard sites and video platforms by users preserving old TV audio. It spread as creators reused it to signal nostalgia for early smart TVs or to fake a television turning on in skits. It remains popular because the bright, distinctive tone is instantly recognizable to anyone who owned one of those models.
