The sound comes from Empire Today's television commercials for carpet and flooring, centred on the sung jingle for 800-588-2300. The catchy repetition of the phone number made the ads unusually memorable, and viewers began quoting and sharing the jingle long after the commercials aired. Online, it spread as a meme sound because the number is instantly recognisable even without any visuals. Creators still use it today as a shorthand for old-school local advertising, a fake commercial ending, or a joke about a number that is impossible to forget.
