Hmmm. Now why would they advertise exclusively to an audience that has already purchased their services?
Because they can't sell the ads yet. Those of you with XM or considering XM should keep in mind that once they can, they will. In addition, they already have a plan in place to increase the number of ads per hour on their commercial stations once they get enough subscribers to make ad sales worthwhile. It's an inherent part of their business plan, just as the Sirius business plan is for no ads at all on any music channels.
Ovrtaxt: It'll be a couple of hours before I can come back and post, so just let me say that, like so much that Newsmax publishes, this article has a lot of bunk in it. XM is not "right wing" and Sirius is not "left wing". I personally prefer, and pay for, Sirius, and generally agree with southernnorthcarolina's post 30. But I'll come back and say a little more in a few hours.
