SIRI vs ALTR Comparison

Sirius XM operates almost exclusively in the US through its SiriusXM and Pandora audio services. SiriusXM is primarily a satellite radio service, which 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 operates the service through a handful of geostationary satellites that it owns and operates, but it now offers a streaming SiriusXM option as well. Pandora, which makes up a much smaller portion of revenue and profit, offers a subscription and ad-supported streaming music service that competes with industry giants like Spotify, Apple Music, and YouTube Music.
