The bright marimba-style tone is closely associated with Apple's iPhone, where it became one of the most recognisable default ringtones and a cultural shorthand for an incoming call. As smartphones spread, the sound moved beyond phones into comedy videos, prank clips and soundboards, where creators shared louder, more exaggerated versions to make the interruption impossible to miss. Its familiarity is the point: listeners recognise it instantly, even out of context, so it still works today for jokes about being constantly reachable, missed calls and phones going off at the worst moment.
