Considering the number they were selling to Wall Street back in 2004 or so was 40 million (20 million for each company) by 2010, I see no real reason to celebrate. Satellite radio is even more of a fringe, niche medium that its originators ever thought. I'm glad it survived, but this number may be as good as it gets, especially with in-car Internet radio looming, at least in well-populated areas.
