Edgar Bronfman Jr., CEO of Warner Music Group, gave a presentation Monday at the UBS Media Week Conference in New York where he said that dominance in the portable music player market will come from operators of wireless telephone networks, not consumer electronics manufacturers, reports TheStreet.com. “Those network operators, said Bronfman, have advantages such as a secure, piracy-resistant network and distribution base of phone-carrying customers much larger than the 5.7 million iPod portable music players that Apple has sold,” notes the report.
