SIRIUS Satellite Radio revolutionized radio broadcasting: it not only pioneered digital service, but it also shifted the broadcasting business paradigm. Instead of focusing solely on advertiser-based revenue in a designated market area, SIRIUS introduced a universal paid subscription service that offers uninterrupted programming to consumers.  Today, following a 2008 merger with XM Radio, SIRIUS boasts a robust customer base of 18.5 million paying subscribers. As part of the Measured Thoughts webcast series, SIRIUS’ Senior VP of Marketing Vance LaVelle sat down to talk about how impactful marketing has been to the company’s overall growth.
