Ringback tones (colouring ring back tone – CRBT) are taking off in China. “According to Zhao, China’s CRBT market will sustain a strong annual growth rate until 2008. After that the business will grow at a steady pace.
But looking into the future, CRBT probably will not be such an important source of revenue as other wireless valued-added services including multiple-media messaging services (MMS), interactive voice response (IVR), and online games for handsets, said Zhao.”
