The chime comes from Disney's DVD releases of the early 2000s, where it rang out over the disc menus and the studio's spinning-logo intro before the film began. As VHS gave way to DVD, that single ding became the unofficial starting bell of family movie nights, and clips of it survive on soundboards as a pure nostalgia trigger. Editors reach for it the way they reach for any familiar ding sound effect: to mark a transition, to sign off a joke, or to open a video with an instant shot of childhood recognition.
