Years ago, I was in a focus group marketing study about satellite radio. Our group's opinion was that at a price-point of $12/mo., the service would be a 'good deal.' They showed us a radio in-dash installation for the company's hardware to receive the broadcasts. It looked a lot like a Pioneer. The variety of programming was another positive point, we decided. Within a couple of years, the national retailers were shilling the installations. I didn't 'bite' until I bought my '09 355 new.
I have the merged Sirius/XM and like it a lot. There is a variety of channels of content though I probably listen to the same 5 stations, but I can listen to them in Miami, in Orlando, or in Manitoba (nah, never been there w/my truck). I like the content and I also like the football coverage from the different leagues & the same w/baseball. When I drive cross-country, for some reason, I like to hear baseball. Anyway, for me, the subscription is worth it. There is a lot of variety and if someone gets into the truck and doesn't want to listen to the Grateful Dead channel, I just hand 'em the list-"pick one." My ears have deteriorated with age that I am sure I don't get the benefit of HD radio if I had it. I never did stand next to the JBL 'Voice of the Theater' banks at a concert, that can permanently ruin your auditory function.
Clear Channel Communications, the national entertainment/broadcasting powerhouse, owned part of XM. Its founder, Jordan E Ginsburg, of Boca Raton FL died late last year. I had business dealings with him and in his 80's he was still an astute businessman.
