According to a new research report from Kagan Research, satellite radio subscribers are predicted to reach 46.8 million and annual revenue is predicted to reach $7.6 billion by 2014.

The report, “Satellite Radio Outlook 2005,” however, predicts that emerging technologies, particularly the wireless industry, will present a competitive threat to satellite radio.

“As wireless technology expands and access to free music Web sites and on-demand services increases, satellite radio will lose potential customers to alternative sources in the battle for consumers’ attention,” Kagan analyst Michael Buckley said in statement. The report notes that exclusive deals with automobile manufacturers will help protect satellite radio from losing some market share to competitive technologies.
