General Electric Co.'s (NYSE: GE) NBC is thanking its lucky stars that the New York Rangers are in the National Hockey League playoffs as the month of May dawns. Otherwise, its ratings would probably be as pathetic as national numbers usually garnered by rodeo, lacrosse or the network's Thanksgiving Day tape dog show.

NBC yesterday saw a 44 percent surge in large-market Nielsen ratings for the double-overtime New York Rangers-Buffalo Sabres playoff game, won by the Rangers 2-1. NBC drew viewers in 1.3 percent of homes in the 56 largest U.S. media markets, which encompasses about two-thirds of the 111.4 million U.S. households with televisions. The game lasted more than four hours, ending at 6:15 pm Eastern Time, thus entering near-prime hours in the East.

Last year's comparable telecast on NBC, a contest between Anaheim and Colorado drew 0.9 percent of the same potential audience. Just to show how critical the New York market is, NBC's national coverage of the San Jose-Detroit game on Saturday had a 1.0 large-market rating, down 9.1 percent from coverage of a New Jersey-Carolina game a year ago.

Clearly, it's a case of as far as the Rangers go in these Stanley Cup playoffs, so goes the NHL's national television ratings on NBC, which has a revenue-sharing agreement with the league. Unlike other sports, the network pays the league zero dollars for rights to broadcast its games. Nonetheless, it's amazing that the sport is broadcast on network television at all.

Unfortunately for NBC, the ratings bump may not last.

The Rangers trail Buffalo two games to one and face an uphill battle to make it to the finals. Another big market team, the Detroit Red Wings, is in the playoffs as well, but chances are remote that they will wind up facing one another.
