The Nokia tune grew famous as the default ringtone on Nokia mobile phones during the 1990s, when the brand dominated the early mobile market and the melody became one of the most heard sounds in the world. Its simple guitar-inspired phrase was easy to recognise even from another room, which helped it cross languages and cultures without needing words. As smartphones replaced older handsets, the tune survived as a shorthand for retro technology, appearing in memes, edits and comedy sketches that use it to signal an old phone, a simpler era or an unexpected interruption.
