On November 8, 1998, CBS televised the first NFL game to be broadcast in high-definition, between the New York Jets and Buffalo Bills at Giants Stadium. It was also the first time two Heisman Trophy winning quarterbacks started against each other in the NFL (Vinny Testaverde for the Jets and Doug Flutie for the Bills).
