摘要：
A broadcast system is disclosed that allows a broadcaster to provide multiple levels of subscription services. Subscribers have the option of listening to fewer (or no) commercials if they pay a higher fee, or listening to more commercials if they pay a lower (or no) fee. Commercials can be demographically targeted, cannot be skipped, and can be audited for billing purposes.
