Its business model is to provide pay-for-service radio, analogous to the business model for premium cable television. Music channels are presented without advertising, while its talk channels, such as Howard Stern's Howard 100 and Howard 101 and Jason Ellis' Faction talk 103, carry commercials. Because all channels are free from FCC content regulation, songs are played unedited for language; talk programs may also feature explicit content if they wish. Subscriptions are prepaid and range in price from US$14.99 monthly (US$9.99 for each additional receiver) to US$699.99 for lifetime (of the receiver equipment). There is a US$15 activation fee for every radio activated. Sirius announced it had achieved its first positive cash flow quarter for the period ending December 2006.
