XM Satellite Radio Holdings Inc. said Monday it has topped 4 million subscribers to its pay-radio service, and still expects to reach 5.5 million customers by the end of the year.
Washington-based XM Satellite, No. 1 ahead of rival Sirius Satellite Radio Inc. as a provider of satellite nationwide talk, news, and music stations, said it aims to reach 20 million subscribers by 2010.
It ended 2004 with about 3.2 million subscribers. Sirius, which launched its service about a year after XM Satellite, ended the first quarter with 1.45 million and expects to reach 2.7 million this year.
