The cue comes from the station identification used by PBS Kids, the children's programming brand of the American public broadcaster PBS, where an animated version of the Dot mascot appeared in short system idents between shows. Those idents ran for years on member stations, so the jingle became part of daily viewing for a generation of children. It later spread online through logo archives, nostalgia uploads and editing communities that collect classic television idents, and it remains popular because few other children's channel sounds are so short, distinctive and widely remembered.
