Sirius Satellite Radio was a satellite radio (SDARS) service that operated in the United States and Canada. Sirius launched in 2002, and primarily competed with XM Satellite Radio, until the two services merged in 2008 to form Sirius XM.
Like XM, Sirius offered pay-for-service radio for a monthly subscription fee, analogous to the business model of cable television. Its music channels were presented without commercial advertising, while its talk channels carried commercials. Its content was not subject to the same FCC content regulation as terrestrial radio, which allowed both music and talk broadcasts to include explicit content. Sirius channels were identified by Nielsen Audio with the label "SR" (e.g. "SR120", "SR9", "SR17").
Sirius Satellite Radio Inc. was headquartered in New York City, and operated smaller studios in Los Angeles and Memphis.
