Remember When You Called Someone and Heard a Song? (vice.com)
An anonymous reader shares a Motherboard article: If you were youngish in the early 2000s, you probably remember this phenomenon -- calling a friend's cell phone, and instead of hearing the the standard ring, you heard a pop song. Called ringback tones, this digital music fad allowed cell phone owners to subject callers to their own musical preference. Ringback tones were incredibly trendy in the early and mid-2000's, but have since tapered off nearly to oblivion. Though almost nobody is buying ringbacks anymore, plenty of people still have them from back in the day. [...] In the process of writing this story, I heard from several people that they or someone they knew still had a ringback tone, in large part because they have had it for years, and don't know how to get rid of it.
And now you drive around in your electric scooter looking for more ice cream?
This started as a "Thing(TM)" in Japan and South Korea in the late 90s and early 2000's. Technically, it's called "color ringback" and - as opposed to custom answering machine setups, etc. - is implemented at the carrier level. As an earlier poster described, this is the sound that you would hear rather than the standard (in the US) 4/2 second ringtone you hear when you dial a number waiting for someone to answer. Working in the industry at the time, we started getting requests for it, so implemented it, but it never took off here in the US, so it dropped off in use to pretty much zero.
Verizon, ATT, Sprint and T-Mobile still offer them. Typical cost is $0.99 per month for the service plus $1.99 per year for each ringback tone.
Me neither. The Register says: Custom RBTs never really took off in the UK. Only T-Mobile gave them any credence but never bothered to promote them much. They aren't kidding, I have never heard one or even heard of them.
