Overview
Sirius Satellite Radio was an American subscription audio service and one of the companies that established satellite radio as a national consumer medium. It delivered digitally compressed music, news, sports, talk, entertainment and specialty programming to receivers installed in vehicles, homes and portable devices. The service operated primarily in the United States and Canada and was headquartered in New York City, with additional production facilities in Los Angeles and Memphis. The business originated in 1990, when Martine Rothblatt founded Satellite CD Radio in Washington, D.C. The company petitioned the Federal Communications Commission to allocate unused spectrum for satellite-delivered radio, a proposal that provoked opposition from terrestrial broadcasters. Rothblatt had previously been involved in satellite communications and navigation ventures. She left the company in 1992 to establish a medical research foundation, after which Robert Briskman, an engineer associated with the company's satellite system, became chairman and chief executive. Later in 1992, investor and Rogers Wireless co-founder David Margolese gained control, renamed the company CD Radio, and led its regulatory, financing and technical development. The company spent much of the 1990s securing FCC authorization, raising capital and building a satellite network. It ultimately raised approximately $1.6 billion for the construction and launch of three highly elliptical-orbit satellites from Kazakhstan in 2000, and paid $83.3 million for its satellite-radio license. The FCC later authorized XM Satellite Radio as a second provider, creating the principal competitive structure of the industry. In 1999, the company adopted the Sirius name to distance the service from compact-disc technology, which was becoming less central to digital audio. By 2000, Sirius had reached agreements with BMW, DaimlerChrysler and Ford to support vehicle installations. Sirius began commercial service on February 14, 2002, in Denver, Houston, Jackson and Phoenix, and expanded across the contiguous United States on July 1. Its subscription model resembled cable television: customers paid a recurring fee for a large, curated channel lineup. Music channels were generally commercial-free, while talk programming could include advertising. Satellite distribution also allowed Sirius to carry content that was not subject to the same FCC indecency framework as terrestrial broadcast radio, including explicit music and talk content. Programming became the brand's main competitive asset. Sirius developed original channels and secured exclusive or preferential arrangements involving Howard Stern, Martha Stewart, Steven Van Zandt, Jimmy Buffett and Eminem. Howard Stern's move from terrestrial radio to Sirius in January 2006 was especially important: the five-year agreement, announced in 2004, gave Stern a substantial programming role and helped drive subscriber growth. Sirius also carried national sports, including NFL, CFL, NBA and selected college programming, NASCAR, soccer and specialty sports talk. Its lineup included news and public-affairs services, Canadian broadcasters, Fox News audio programming, LGBT-oriented talk through Sirius OutQ, and children's entertainment through the later Backseat TV service. The company expanded beyond vehicle receivers. Sirius Internet Radio launched in 2006, allowing subscribers to stream a portion of the channel lineup online. Sirius also supplied commercial-free music for businesses through a partnership with Applied Media Technologies Corporation and offered a satellite television service for rear-seat vehicle entertainment. In Canada, Sirius entered through a partnership involving Standard Broadcasting and the Canadian Broadcasting Corporation after regulatory approval in 2005. The service also received authorization for terrestrial repeaters in selected Puerto Rican locations in 2009, although that development occurred after the merger under the broader SiriusXM corporate structure. Sirius and XM announced a merger on February 19, 2007. The transaction was controversial because it combined the two principal U.S. satellite-radio providers and therefore required review by the Department of Justice and FCC. The Justice Department approved it in March 2008 and the FCC followed in July. The merger closed on July 29, 2008. Sirius and XM initially continued as separate consumer brands, but their channel lineups were made available across the combined platform in November 2008. The original brands were eventually retired in favor of SiriusXM in February 2011. Sirius Satellite Radio therefore survives as the predecessor service and brand within the history of SiriusXM, rather than as an independent operating company.
History
Sirius began as Satellite CD Radio, founded by Martine Rothblatt in Washington, D.C., in 1990. Its initial objective was to persuade the FCC to permit satellite-based digital audio broadcasting using unused frequencies. The proposal challenged the established terrestrial-radio model and attracted opposition from broadcasters concerned about new competition. Rothblatt left the company in 1992 to focus on medical research, and Robert Briskman assumed leadership. Later that year, David Margolese, who had backed the venture and had experience in wireless communications through Rogers Wireless, took control and renamed it CD Radio. Margolese's leadership was defined by regulatory lobbying, capital formation and infrastructure development. CD Radio spent years seeking authorization to operate and eventually obtained a satellite-radio license for $83.3 million. The company raised about $1.6 billion to finance three satellites, which were launched from Kazakhstan in July 2000 into highly elliptical orbits. In 1999, management changed the name to Sirius Satellite Radio, reflecting the declining strategic importance of compact discs and creating a more distinctive consumer identity. Automobile distribution became central to the launch plan, and Sirius secured relationships with BMW, DaimlerChrysler and Ford by 2000. David Margolese left the chief executive position in 2001, and Joe Clayton succeeded him. Sirius launched on February 14, 2002, in Denver, Houston, Jackson and Phoenix; nationwide coverage of the contiguous United States followed on July 1. The service charged monthly subscription fees and used a channel-based model similar to cable television. It differentiated itself through commercial-free music, national coverage, digital sound, specialized programming and the ability to carry explicit material outside the conventional terrestrial-radio regulatory structure. The company broadened its programming portfolio throughout the 2000s. It developed music channels and specialty services, acquired sports and news rights, and established channels associated with prominent personalities. Sirius OutQ, launched in 2003, was an early nationwide 24-hour talk service aimed at an LGBT audience. Sirius NFL Radio began in 2004. The most commercially consequential programming agreement was with Howard Stern, whose exclusive Sirius show began in January 2006. Sirius also worked with Steven Van Zandt on The Underground Garage and Outlaw Country and developed services associated with Martha Stewart, Jimmy Buffett and Eminem. Canadian services, public radio, Fox audio simulcasts, sports talk and international soccer further expanded the lineup. Sirius pursued multiple distribution formats. Sirius Internet Radio, launched in 2006, extended selected programming to authenticated subscribers online. The company offered business music through Applied Media Technologies Corporation and developed Backseat TV, a vehicle entertainment service carrying Nickelodeon, Disney Channel and Cartoon Network content for compatible Chrysler vehicles. It also developed improved satellite and terrestrial-repeater arrangements for difficult reception environments. Competition with XM remained intense and contributed to high infrastructure and subscriber-acquisition costs. On February 19, 2007, Sirius announced an agreement to merge with XM. The proposal was controversial because it would eliminate direct competition in U.S. satellite radio. The Department of Justice approved the transaction on March 24, 2008, and the FCC approved it on July 25. The merger closed on July 29, 2008. The legacy services operated separately for a period, while combined channel access was introduced in November 2008. By February 2011, the Sirius and XM consumer identities had been replaced by SiriusXM. Sirius Satellite Radio consequently became a historical predecessor to the continuing SiriusXM service.
