Well, it was pre-announced last month, and now it's here: the ReachMD channel for medical professionals is now available on XM Satellite Radio (ch 233).
The ReachMD channel features roundtable discussion, breaking medical news and special programming - available 24/7. Since it's targeting the busy healthcare professional, the channel offers short-form programming, and provides new information every 15 minutes.
To coincide with the channel launch, ReachMD will be exhibiting at the American College of Cardiology's 37th Scientific Meeting, March 23-27th, 2007 in New Orleans, Louisiana.

Hmm.. I wish that block-and-rebate was available now!
