According to analysts, operators are limited by the number of customers on their network whereas OEMs (original equipment manufacturers) are only limited by the penetration of their device. Though operators cannot be ruled out, OEMs definitely score over them in more than one ways. According to a latest research, during the quarter ended March 2010, the number of mobile users across the EU5 (U.K., France, Germany, Spain and Italy) markets, listening to music on their handsets reached 54 million, up 10% from a year earlier. 23.8% of total mobile customers is represented in those markets through this figure when compared to just 13.2% of mobile users in the U.S. who listen to music on their phones.
