Call off the satellite-radio war in Canada. It's over; it's done like dinner. Now that XM has signed a marketing agreement with ex-NHL star Mark Messier is there any reason for full-page newspaper inserts, billboard ads or television spots? Messier has come on board to promote XM's broadcasts of NHL games and its "exclusive" NHL talk radio channel, Home Ice. Look at what Messier did for Lay's Potato Chips where he revitalized the brand in Canada with a series of quasi-humorous TV ads that played off Messier's tough reputation. I can just see the stampede of consumers rushing to buy XM radios this holiday season now that Messier's on board.
