The PlayStation 2 startup sound comes from Sony's PS2 console boot sequence, first heard when the system launched in 2000. It became one of the most recognizable console intros of its era because millions of players heard it before games, DVDs and memory card screens. Online, the sound spread through retro gaming compilations, meme edits and nostalgia posts centered on early 2000s gaming culture. It still gets used because a few seconds of audio can instantly place a viewer in the PS2 era.
