Ringback Tones

This is something I had not heard of before - ringback tones are mobile phone ringtones you can buy for the person calling you to hear in place of the normal ringing sound (kind of like a ringtone in reverse).  They are apparently hugely popular in Asia and as of now, Verizon and T-Mobile have plans to bring the service to customers in the U.S. 

This takes people's desire for custom and individualized products to yet another level.  Normal ringtones are for you (and, I suppose, those around you), but ringback tones are a way of customizing, for others, the experiencing of getting in touch with you. Let the billions of dollars of ringback tone sales begin!
