The Nintendo 3DS, released by Nintendo in 2011, was a handheld console known for its glasses-free 3D screen, and its startup sound played every time the system was turned on. Because millions of players heard it daily, the chime became closely tied to childhood gaming memories and handheld play. It later spread online through nostalgia edits, gaming compilations and reaction videos, where a few seconds of the sound instantly signals a return to the 3DS era. It remains popular because it is short, distinctive and immediately recognisable.
