In a report by The Mac Observer, the iPod is ranked number one in dollar market share for MP3 Players. “Apple’s dollar market share reached 27 percent compared with 10 percent for second-ranked SONICBlue and its Rio players , according to market research firm NPDTechworld.”
“Making the market share numbers even more interesting is that they are based only on sales made by third-party retailers such as Best Buy and Target, and do not include iPods sold direct by Apple through its retail stores or online. Market share and unit share numbers of Apple’s competitors also do not include direct sales figures.”
