It might still be possible for him to broadcast on Sirius and an AM or FM station; Jonathan Schwartz has been on both XM Radio and WNYC for a while now. I think he was on NYC first, though, and continuously--must look and see if there's any history of it online.

The problem with satellite radio is having to choose. If Schwartz left NYC, I'd want to go with XM, but I'd want Sirius for Cousin Brucie. Arg.
