The following is a list of NHL Winter Classic, Stadium Series and Heritage Classic broadcasters, including those in Canada and in the United States. The first NHL Heritage Classic was played in 2003 at Commonwealth Stadium between the Edmonton Oilers and the Montreal Canadiens. Although the Oilers had suggested the idea of hosting an outdoor game as early as the mid 1980s, the genesis of the 2003 event was the "Cold War" outdoor game played two years prior between Michigan State University and the University of Michigan.
