XM typically refers to XM Satellite Radio, a satellite radio service broadcasting across North America. It offers a wide variety of digital audio channels, including music, news, sports, talk, and entertainment, many of which are commercial-free. Now part of Sirius XM, it provides subscribers with access to its programming through satellite receivers in cars, homes, and on mobile devices via streaming. While the XM brand isn't as prominent as it once was due to the merger, its legacy lives on within the Sirius XM platform.
