| | Personalized Ringback Tones Ring with Revenue Potential |
 | | Custom ringback tones--which treat callers to song clips, sound effects, film dialog, or personalized messages and can be customized according to wireless subscribers' whims--could eventually account for $2.4 billion in annual revenue worldwide, becoming as popular as or even surpassing the popularity of downloadable ring tones. |
 | | Ringback tones allow users to replace the familiar ringing sound callers hear after dialing with a snippet of a song, a sound effect, a bit of film dialog, or a recorded voice message. |
 | | Ringback tone subscribers can customize greetings for caller groups or individuals—opting, say, to respond to a call from a significant other with a sample of Echo and the Bunnymen's "Lips Like Sugar" or the Rolling Stones' "Heartbreaker," depending on the current state of the relationship. |
