The MGM lion roar is one of the most recognisable sounds in cinema, fronting Metro-Goldwyn-Mayer pictures since the silent era with mascot Leo the Lion. When the studio launched its MGM Kids On Demand service, the classic roar was reworked into a short, cheerful channel ident dated 2004, pairing the famous growl with a bright jingle aimed at young viewers. Logo enthusiasts later ripped the ident into online soundboards and nostalgia compilations, where it survives as a five-second burst of early-2000s children's television branding alongside other classic TV stings such as the famous DUN DUN.
