Apple's G3 machines arrived in the late 1990s, when the Power Mac G3 and the colourful iMac G3 made Macs feel friendly and modern again after years of plain beige boxes. Their short startup chime became a familiar daily sound for students, designers and home users, and later a shorthand for that era in online videos. Today creators reuse it because it instantly dates a scene, signals an old computer turning on, and triggers recognition even from viewers who never owned one.
