Toshiba is a long-running Japanese electronics maker, and 'CM' is the common Japanese shorthand for a TV commercial, so this clip circulates as the old version of one of its ad stings. Short brand jingles like this were built to be remembered after a single hearing and are now shared on soundboards detached from the original advert. Online it survives less as advertising and more as a retro reference, used by editors who grew up with Japanese TV spots or who like the dated, polite formality of the sound.
