The ring imitates the bell system used in mid twentieth century landline telephones, where an electric signal struck internal bells to alert households to a call. As those phones disappeared, recordings of the sound survived in films, cartoons and stock libraries as shorthand for a call in the past. Online it became a popular meme and editing staple for fake calls, period scenes and ironic contrasts with smartphones. Its short looping pattern also made it ideal as an actual mobile ringtone, including on Honor devices where a retro tone stands out.
