Sirius XM operates almost exclusively in the US through its SiriusXM and Pandora audio services. SiriusXM is primarily a satellite radio service that offers nationwide coverage and mostly ad-free listening, with proprietary channels and exclusive content. It makes agreements with automakers to install its radios in vehicles and give trial services to vehicle buyers, which have traditionally fed its subscriber base. The company provides the service via a fleet of geostationary satellites it owns and operates and now offers a streaming SiriusXM option. Pandora, which accounts for a much smaller portion of revenue and profit, offers a subscription and ad-supported streaming music service that competes with industry giants such as Spotify, Apple Music, and YouTube Music.
