the MP3 market alone, Sean Wargo, director of industry analysis for the Arlington, Virginia-based Consumer Electronics Association, sees potential for small firms that can rise above the noise generated by Apple’s iPod. Sales of portable MP3 players more than doubled in 2004 to nearly 7 million units, accounting for $1.2 billion in revenues, according to the CEA. “Those brands that harness the opportunity and offer targeted products to a specific consumer group will definitely find opportunity in this growing market,” Wargo says.
