ROBERT SIEGEL, HOST:
There was a time when cell phones were used to make calls and many of the calls were defined by this.
(SOUNDBITE OF NOKIA RINGTONE)
SIEGEL: The Nokia ringtone, it was introduced in 1994. Last Friday, Nokia - once the world's cell phone leader - sold its dwindling phone business to Microsoft for a lot of money, seven and a half billion dollars.
Until today, no one had said what becomes of that ringtone, a tune Nokia says is played about 20,000 times a second worldwide.
SACHA FRERE-JONES: I'm pretty sure it's the first ringtone I ever heard.
SIEGEL: Sasha Frere-Jones is pop critic for The New Yorker magazine and he's written about ringtones.
FRERE-JONES: Francisco Tarrega wrote this in 1902. It's a waltz in three. And the figure that we know comes about 15 seconds into the piece.
(SOUNDBITE OF NOKIA AD)
UNIDENTIFIED MAN: Nokia, it remembers because it's human to forget.
SIEGEL: The composition "Gran Vals" was first used by Nokia in 1992 in that commercial, its first-ever TV commercial for mobile phones. A couple of years later, it was adopted as a ringtone.
The New Yorker's Shasa Frere-Jones predicts it will serve a purpose in future TV shows and movies.
FRERE-JONES: This now will be a signifier for a phone in the '90s.
SIEGEL: And if you're feeling a little nostalgic for the '90s, Microsoft tells us the ringtone will continue to be an option on Nokia-branded devices.
