Does Sirius/XM Radio know which station each of its subscribers is
listening to? I'm not looking at this as a nefarious "big brother is
watching you" thing. Rather I'm wondering if they do so to measure the
ratings of their programming. Considering each subscriber's radio has
its own identification number it seems doing so would be relatively
easy and a smart business practice. Anyone know?


The infrastructure is one-way. The radios are capable of storing such
infor, and may download it if connected to web for a firmware upgrade,
etc., but there is no two-way connection like satellite TV.
