An wide-ranging interview with Thomas Gewecke, senior VP of Sony BMG, Mark Desautels, VP of Wireless Internet Development at CTIA, and Vern Poyner, CEO of WiderThanAmericas, on the mobile music market. Among the topics discussed: How will subscribers pay for this content – per song, on a subscription basis, or some other yet-to-be-devised plan? What is the income model for the content creators – such as the musicians and songwriters whose works will now be seen on portable devices? How will the carriers participate? How will the record companies get paid? How can mobile music file transfers be secured against the type of file-swapping endemic to the PC platform?
