Sports on the radio

So yesterday I got to drive Kim's car, as she drove her mother back to Pennsylvania in mine. This meant that I got to listen to the satellite radio. Flipping through the channels I came across one in the middle of the sports area that was broadcasting poker on the radio... I can barely understand the success of this on the tv, although I will admit to having it on a couple of times, but on the radio? Then again, is it really that different from any other sport where the announcers have to paint a picture in your mind? Maybe not...
