Fans continue to tune into NFL football more than any other program this holiday season. The Giants-Cowboys Sunday night game on NBC was the most-watched show among all programs last week with 24.5 million viewers — the 12th time in 14 weeks that an NFL game telecast has been television’s most-watched program. In addition, NFL games led the ratings in 29 local markets. Pittsburgh led the way with a 49.7/68 rating for last Thursday’s Browns-Steelers game.
