XM Satellite Radio was founded in 1988, however service did not launch until September 25, 2001. In July 29, 2008 XM Satellite Radio merged with its competitor Sirius Satellite radio.
On November 12th 2008, XM merged the channel selection of XM Radio and Sirius Sattelite Radio. This merger created a lot of redundant channels, so many were dropped. Other channels are dropped due to lack of listenership. Also, layoffs at XM meant a good of number of "DJ's" were off the air. This caused further channel consolidation.
There are XM boomboxes that are available for sale. They are specifically designed to accommodate for XM radio and the needs of the customers who are faithful to XM.
