CHAMPIONSHIP OVERNIGHTS: NFL TITLE GAMES OFF FROM '97

          Overnight ratings showed that viewership of Sunday's
     NFL Conference Championship games "tumbled," according to
     USA TODAY's Rudy Martzke.  NBC's 25.9 overnight for Broncos-
     Steelers was off 9% from last year's 28.4 for Jaguars-
     Patriots.  Fox's 27.4 for Packers-49ers fell 10%, from 30.6
     for last year's Panthers-Packers.  BBDO's Steve Grubbs
     called the Packers-49ers number "shocking," and added, "We
     had projected a 45.0 to 45.5 rating for the Super Bowl.  Now
     we'll have to bring that down a point" (USA TODAY, 1/13).  
          MARKET-BY-MARKET: In Denver, the AFC Championship game
     earned a 56.4/86 on KUSA-TV.  In Pittsburgh, the game did a
     51.9/79 (Dusty Saunders, ROCKY MOUNTAIN NEWS, 1/13).  The
     NFC title game scored a 56.8/80 in Milwaukee, and a 46.7/77
     in San Francisco (Howard Manly, BOSTON GLOBE, 1/13).
