To answer the question from the last (and I believe now closed) TK thread about XM, the answer is yes.
From XM's press release today:
WASHINGTON, Feb. 15 /PRNewswire-FirstCall/ -- Tony Kornheiser -- sportswriter, columnist, ESPN commentator, humorist, and author -- will be heard nationwide on XM Satellite Radio starting March 5.
Kornheiser's new radio show, originating from Washington Post Radio (WTWP) in Washington, D.C., will air from coast to coast on XM's sports talk radio channel XM Sports Nation (XM Channel 144) Monday through Friday from 9 am to 11 am ET. Tony will also host special shows exclusively for the XM Radio audience on a regular basis.
It's the kind of thing that can be very funny and clever if done sparingly (like once every two seasons or so) but if they resort to doing it once a season or more, it will get old fast. They did it well with The Superfriends opening a few years ago.
