Assuming Ch. 9 goes through with its showing of the Pats-Giants game despite no longer having local broadcast exclusivity, it will be a night unlike any in 51 years in New York sports TV.

David Halberstam, executive VP of Westwood One radio and a sports media historian, wrote in an e-mail that the last time three New York stations showed the same sports event was the 1956 World Series, which was on Channels 4, 9 and 11.

Westwood One will carry the game on radio outside New York and Boston.
