As they say on their site at www.xmradio.com, first there was AM, then there was FM, and now there is XM. You can think of XM as an entirely new radio band of direct broadcast satellite radio blanketing the North American continent with up to 100 separate programming channels--each broadcasting like a distinct radio station with a specific format. You'll need a new radio or adapter for the old one, and these will start appearing in new cars and stores inow.
So what does Synergy have to do with this? I'll be providing the "sounders"--the sonic logos that you'll be hearing on all of the 100 channels as well as the unifying sound logo for the entire XM broadcast service network. It's a very exciting project which will change the way that radio works. It also brings me back to my roots in radio which included college radio at WJRH FM in Easton, Pennsylvania in the late 1960s and early 70s and the now-defunct WSAN AM 1470 in Allentown, Pennsylvania. Synergy is considered to be one of the "XM Originals" Creative Partners in developing this new broadcast entity. (I predict that XM will become a power in internet broadcasting, too.)
